No light on at the checkout line...

When I notice a cashier ringing up customers and see the register number light is off I don't get in their line. If they have a closed placard on the conveyor belt this is a sure signal that they are closing down. However, there are people who will put their groceries on the belt anyway. Even go as far as to move the placard. The cashier will say they are closing down the line but the people don't budge. This is the equivalent of going into a steak restaurant and ordering a well-done rib eye five minutes before closing. It's rude to enter a place of business so late. Also, who cooks their steak well? Savages that's who.
