Our grocery store was kinda like what you describe Lazs, only without the gas pumps. The owners slaughtered their own hogs in the back and did some really excellent BBQ pork sandwiches at lunch time when I was in school for like 50 cents each. That was the big deal once you got into high school, you could walk off the school grounds to eat. They didnt let us drive (if you were old enough), so alot of us drove and parked in town by the store, and then walked there for lunch. Then we could go cruising for half an hour before we had to park and walk back to school.
I think the entire grocery store could have fit in my office. They had a small shelf with shotgun shells and .22s by the cash register and one of those big metal coolers behind the counter with the glass bottles of soda for 30 cents. You had a choice of Pepsi, Coke, RC, Mt. Dew and Ski. They didnt sell guns, but there was a bulletin board inside the door, and there was usually several posted for sale.
