If you can manage to trap your waitress or waiter behind the counters, when people come in and sit down as soon as she picks up the food it automatically goes to the customer. This is a fast way to get the food to your customers. There cannot be any gaps between the counters you stick her between. When you start off with three, you must use your stoves to trap her as well. A good way to trap her is to get her stuck between the wall.
