My dad's uncle's grocery store had two registers, but normally only one cashier on duty. On rare busy occasions, whoever was working the meat counter (my dad or his uncle), would open the second register for a few minutes. Most people had small orders, as they would stop in a few times during the week. The check out counter was rather small, and doughnuts and a candy jar were at one side. No conveyor belt, nor was one necessary, as most customers left with only two or three bags. There was no parking lot, only on street parking, and a lot of customers walked there. Some that walked brought wagons or wheeled carts to take their purchases home. The store was about 25' x 70' including the back area. It was in business 64 years, closing in 1974.
