I am very glad that all of you will soon go to the States to study and work with Americans. We need to eat no matter where. So, as the first lecture in the orientation program, I'd like to talk about what Americans do in a restaurant.
In American restaurants, you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you get free refill.
Soft drinks are sweet, carbonated drinks like Coke. Hard drinks are alcoholics, like whiskey. They are served either on the rocks or straight.
Serving in the restaurant are large. If you can't finish, ask the waiter for a "doggie bag", so that you can enjoy the food later. Remember, you should always have a tip of about 15%on the table when you leave.
