Everywhere around here has one line per register. At the beginning of social distancing one large local store built a barricade and enforced a single line so people weren't standing so close together. I went there once during that time and the line wrapped a quarter of the way around the store, ending over in the freezer department. It went faster than it looked, but that store also tends to have enough checkouts open and staffed with efficient, motivated workers.
