Applies to establishments engaged in operating convenience grocery stores or mini-markets with self-service gasoline operations. These establishments provide retail sale of convenience grocery items, not just snack items, in addition to self-service gasoline. Gasoline operations are limited to self-service only where the store employee is a cashier who monitors the pumps and collects the payments inside the store. Self-service/convenience store operations in classification 3410 differ from self-service gas stations in classification 3409 in that establishments in classification 3410 provide a more extensive line of grocery items. In addition to snack foods, staples such as bread, milk, and canned foods are available for sale. They may also prepare food such as sandwiches, chicken, jo jos, or hot dogs, and occasionally fill a customer's propane tank, and offer automobile or truck washing services, all of which is included within the scope of this classification.

This classification excludes establishments which provide any full service or limited services in addition to self-service operations at the same location which are to be reported separately in classification 3406; establishments which provide only self-service gasoline operations and whose grocery items are limited to prepared snack foods such as chips and candy, and cigarettes which are to be reported separately in classification 3409; and convenience stores with no gasoline services which are to be reported separately in classification 6403.
