Accounting Policies [Abstract]
Fiscal Period, Policy [Policy Text Block]	The Company reports its results of operations on a 52- or 53-week fiscal year ending on the last Sunday in September. The first fiscal quarter is 16 weeks, the second and third quarters each are 12 weeks, and the fourth quarter is 12 or 13 weeks. Fiscal years 2014 and 2013 are 52-week years.
Fair Value of Financial Instruments, Policy [Policy Text Block]	The Company holds money market fund investments that are classified as cash equivalents that are measured at fair value on a recurring basis based on quoted prices in active markets for identical assets. The Company also holds available-for-sale securities generally consisting of state and local municipal obligations and variable rate demand notes which hold high credit ratings. These instruments are valued using a series of multi-dimensional relational models and series of matrices with standard inputs obtained from readily available pricing sources and other observable market data, such as benchmark yields and base spread. The carrying amounts of accrued payroll, bonuses and other benefits due team members, and other accrued expenses approximate fair value because of their short maturities. Store closure reserves and estimated workers’ compensation claims are recorded at net present value to approximate fair value.
Cost Method Investments, Policy [Policy Text Block]	Equity investments without readily determinable fair values for which we do not have the ability to exercise significant influence are accounted for using the cost method of accounting and classified as “Other assets” on the Consolidated Balance Sheet. Under the cost method, investments are carried at cost and are adjusted only for other-than-temporary declines in fair value, certain distributions, and additional investments.
Earnings Per Share, Policy [Policy Text Block]	The computation of basic earnings per share is based on the number of weighted average common shares outstanding during the period. The computation of diluted earnings per share includes the dilutive effect of common stock equivalents consisting of incremental common shares deemed outstanding from the assumed exercise of stock options and the dilutive effect of restricted stock awards.
Treasury Stock [Policy Text Block]	Under the repurchase programs, purchases can be made from time to time using a variety of methods, including open market purchases. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic conditions and market conditions, and other considerations. Purchases may be made through a Rule 10b5-1 plan pursuant to pre-determined metrics set forth in such plan. The Board’s authorization of the repurchase programs does not obligate the Company to acquire any particular amount of common stock and they may be suspended or discontinued at any time at the Company’s discretion.
