47. Fast-food Talk p.315

 
    Though it is generally accepted that junk food is not healthful, American fast-food restaurants are
popping up all over the world. These restaurants are for people who are always in a rush. If they don't
have time to sit down to a regular meal, they race over to the nearest McDonald's. There they can quickly
satisfy their hunger.
    Because Americans like things done immediately, they often order their food quickly at fast-food
restaurants. They say, "A burger, fries and a coke!" though it's not polite, it's efficient. So when you
are in the States, try to order this way. After all, in America do as the Americans do.
