Segment Reporting [Abstract]
Segment Reporting	Segment ReportingAs of October 31, 2021, we operated 2,380 stores in 17 states. Our convenience stores offer a broad selection of merchandise, fuel and other products and services designed to appeal to the convenience needs of our guests. We manage the business on the basis of one operating segment. Our stores sell similar products and services, and use similar processes to sell those products and services directly to the general public. We make specific disclosures concerning the three broad merchandise categories of fuel, grocery and general merchandise (previously referred to as "grocery and other merchandise"), and prepared food and dispensed beverage (previously referred to as “prepared food and fountain”) because it allows us to more effectively discuss trends and operational programs within our business and industry. Although we can separate revenues and cost of goods sold within these categories (and further sub-categories), the operating expenses associated with operating a store that sells these products are not separable by these categories.
