The operating results for the periods presented are not necessarily indicative of the results to be expected for the full year. The Company has evaluated subsequent events for disclosure through the date of issuance of the accompanying unaudited consolidated interim financial statements and there were no material subsequent events which require additional disclosure.

Current Relevant Accounting Standards [Abstract]
Current Relevant Accounting Standards	(2) Current Relevant Accounting Standards In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update ("ASU") 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 amends guidance on reporting discontinued operations only if the disposal of a component of an entity or group of components of an entity represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. It also allows companies to have significant continuing involvement and continuing cash flows with the discontinued operations. Additional disclosures are also required for discontinued operations and individually material disposal transactions that do not meet the definition of a discontinued operation. The standard should be applied prospectively for all disposals of components of an entity and for all businesses that, on acquisition, are classified as held for sale that occurred within annual periods beginning on or after December 15, 2014, including interim periods within that reporting period. Adoption of the ASU did not have an impact on the Company’s 2015 consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amended the existing accounting standards for revenue recognition. ASU 2014-09 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The standard was initially effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In August 2015, the FASB issued a one-year deferral of the effective date of this new guidance resulting in it now being effective for the Company beginning in fiscal year 2018. Early adoption is not permitted. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently in the process of evaluating the impact of adoption of the ASU on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40)(Topic 718): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 provides guidance related to management’s responsibility to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and to provide related footnote disclosures. The new requirements are effective for the annual periods ending after December 15, 2016, and for interim periods and annual periods thereafter. Early adoption is permitted. Adoption of the new ASU will not have an impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventor y. ASU 2015-11 amends guidance on the measurement of inventory from lower of cost or market to net realizable value. The amendment applies to all inventory other than those measured by Last-In-First-Out (LIFO) and the Retail Inventory Method (RIM). The amendment is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted. Adoption of the new ASU will not have an impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires that any effect on earnings due to depreciation, amortization or other income effects, due to a change to the provisional amounts be recorded in the current period’s financial statements as if the accounting had been completed at the acquisition date. The portion of the amount recorded in the current-period earnings, which would have been recorded in the previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date, must be presented separately on the face of the income statement or disclosed in the notes to the financial statements by line item. The amendment is effective for the fiscal year beginning after December 15, 2015. The amendments are to be applied prospectively to any adjustments occurring after the effective date. Adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.

Investments [Abstract]
Investments	(3 ) Investments The Company’s marketable securities are all classified as available-for-sale within Current Assets in the Company’s Consolidated Balance Sheets. FASB has established three levels of inputs that may be used to measure fair value: Level 1 Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. The Company’s marketable securities valued using Level 1 inputs include highly liquid equity securities, for which quoted market prices are available . The Company’s bond portfolio is valued using Level 2 inputs. The Company’s bonds are valued using a combination of pricing for similar securities, recently executed transactions, cash flow models with yield curves and other pricing models utilizing observable inputs, which are considered Level 2 inputs. For Level 2 investment valuation, the Company utilizes standard pricing procedures of its investment advisory firm(s) which include various third party pricing services. These procedures also require specific price monitoring practices as well as pricing review reports, valuation oversight and pricing challenge procedures to maintain the most accurate representation of investment fair market value. In addition, the Company engages an independent firm to value a sample of the Company’s municipal bond holdings annually in order to validate the investment’s assigned fair value. The Company accrues interest on its bond portfolio throughout the life of each bond held. Dividends from the equity securities are recognized as received. Both interest and dividends are recognized in “Investment income (loss)” on the Company’s Consolidated Statements of Income. Marketable securities, as of September 26, 2015 and December 27, 2014, consisted of: (dollars in thousands) September 26, 2015 Amortized Cost Gross Unrealized Holding Gains Gross Unrealized Holding Losses Fair Value Available-for-sale: Level 1 Equity securities $ 1,198 $ 6,207 $ - $ 7,405 Level 2 Municipal bonds 80,959 1,448 (64) 82,343 $ 82,157 $ 7,655 $ (64) $ 89,748 (dollars in thousands) December 27, 2014 Amortized Cost Gross Unrealized Holding Gains Gross Unrealized Holding Losses Fair Value Available-for-sale: Level 1 Equity securities $ 1,198 $ 6,683 $ - $ 7,881 Level 2 Municipal bonds 64,561 1,613 (96) 66,078 $ 65,759 $ 8,296 $ (96) $ 73,959 Maturities of marketable securities classified as available-for-sale at September 26, 2015, were as follows: Amortized Fair (dollars in thousands) Cost Value Available-for-sale: Due within one year $ 6,455 $ 6,514 Due after one year through five years 53,775 54,803 Due after five years through ten years 20,729 21,026 Equity securities 1,198 7,405 $ 82,157 $ 89,748 The Company also maintains a non-qualified supplemental executive retirement plan and a non-qualified pharmacist deferred compensation plan for certain of its associates which allows them to defer income to future periods. Participants in the plan s earn a return on their deferrals based on mutual fund investments. The Company chooses to invest in the underlying mutual fund investments to offset the liability associated with the non-qualified deferred compensation plan s . Such investments are reported on the balance sheet as SERP investments, are classified as trading securities and are carried at fair value using Level 1 inputs with gains and losses included in investment income. The changes in the underlying liability to the employee are recorded in operating expenses .

Self-Insurance [Abstract]
Self-Insurance	(7) Self-Insurance While researching alternative methods to calculate retained claim liability for the Company’s self-insured workers compensation and general liability insurance programs, we discovered errors in the application of actuarial methods used to estimate the obligation of future payments resulting from claims due to past events. These errors primarily related to the Company’s selection of loss development factors and the application of such factors to the population of claims. The impact of these prior period misstatements to our consolidated financial statements resulted in the understatement of workers compensation and general liability expense with a corresponding understatement of self-insurance liabilities over multiple fiscal periods through June 27, 2015 . In accordance with applicable accounting guidance, an adjustment to the financial statements for each individual prior period presented is required to reflect the correction of the period-specific effects of the change, if material. Based on our evaluation of the relevant quantitative and qualitative factors, we determined the identified corrections are immaterial to the Company’s individual prior period consolidated financial statements, however, the cumulative correction of the prior period errors would be material to our current year Consolidated Statements of Income. Consequently, we have restated certain prior period amounts to correct these errors. Additionally, we have restated our retained earnings as of January 1, 2012 in the amount of $14.2 million. The tables below summarize the effect of the restatement of previously reported consolidated financial statements for the fiscal years ended December 27, 2014, December 28, 2013 and Decem be r 29, 2012 , the thirteen and thirty-nine weeks ended September 27, 2014, the thirteen and twenty-six weeks ended June 27, 2015 and June 28, 2014, and the thirteen weeks ended March 28, 2015 and March 29, 2014 .

Current Relevant Accounting Standards [Abstract]
Current Relevant Accounting Standards [Policy Text Block]	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update ("ASU") 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 amends guidance on reporting discontinued operations only if the disposal of a component of an entity or group of components of an entity represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. It also allows companies to have significant continuing involvement and continuing cash flows with the discontinued operations. Additional disclosures are also required for discontinued operations and individually material disposal transactions that do not meet the definition of a discontinued operation. The standard should be applied prospectively for all disposals of components of an entity and for all businesses that, on acquisition, are classified as held for sale that occurred within annual periods beginning on or after December 15, 2014, including interim periods within that reporting period. Adoption of the ASU did not have an impact on the Company’s 2015 consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amended the existing accounting standards for revenue recognition. ASU 2014-09 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. The standard was initially effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In August 2015, the FASB issued a one-year deferral of the effective date of this new guidance resulting in it now being effective for the Company beginning in fiscal year 2018. Early adoption is not permitted. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is currently in the process of evaluating the impact of adoption of the ASU on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40)(Topic 718): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 provides guidance related to management’s responsibility to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and to provide related footnote disclosures. The new requirements are effective for the annual periods ending after December 15, 2016, and for interim periods and annual periods thereafter. Early adoption is permitted. Adoption of the new ASU will not have an impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventor y. ASU 2015-11 amends guidance on the measurement of inventory from lower of cost or market to net realizable value. The amendment applies to all inventory other than those measured by Last-In-First-Out (LIFO) and the Retail Inventory Method (RIM). The amendment is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted. Adoption of the new ASU will not have an impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires that any effect on earnings due to depreciation, amortization or other income effects, due to a change to the provisional amounts be recorded in the current period’s financial statements as if the accounting had been completed at the acquisition date. The portion of the amount recorded in the current-period earnings, which would have been recorded in the previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date, must be presented separately on the face of the income statement or disclosed in the notes to the financial statements by line item. The amendment is effective for the fiscal year beginning after December 15, 2015. The amendments are to be applied prospectively to any adjustments occurring after the effective date. Adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
