47. Fast-food Talk 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.
