If you are in a hurry and you want to have a quick meal there is no better place than a self-service restaurant. You go into the restaurant, pick up a tray, knife, fork, and spoon and want queue at a counter where thefood is on display. You pick out what you want and put it on your tray, which you have to push alone a special rack till you reach the cashier. The cashier will give you your bill. After paying, you take your tray to any table you like. you can sit alone or with another customer. you can have a good meal in ten minutes. and-as there is no waiter you don't have to give a tip.
