The first fast food restaurants opened in the United Sates at the end of the 1950s. Throughout the 1960s and 1970s, the fast food industry continued to expand across the United Sates. Two aspects of American society that helped the fast food industry take off were teenagers and cars. Teenagers were the best workers to fill the low-skill jobs needed to work in fast food restaurants putting together hamburgers, taking orders and frying potatoes. Fast food chains also marketed themselves to people with cars by having drive-thru order windows and car hops. Car hops were waitresses who usually wore roller skates and brought the food outside the restaurant so that people could eat in their cars. The trend of fast food chains hiring teenagers continues today. One out of every eight Americans has worked at McDonald’s, the largest fast food chain in the United States. Fast food chains used to be found only along highways or in business areas where people need to grab a quick lunch before returning to work. Today, however, fast food restaurants can be found in sports stadiums, airports, gas stations, malls; on college campuses, cruise ships; at K-Mart, Wal-Mart; and in hospital cafeterias. The popularity of fast food in the United States is related to the idea that people would rather eat in a place they are familiar with rather than try a new place they know nothing about. This is the philosophy behind franchises(特许经营). When a person buys a franchise, they are paying for the use of the company’s name. This system has advantages and disadvantages for the person starting the restaurant. The new franchise owner is called the “franchisee”. The company selling its name is the “franchiser”. The franchiser brings experience, equipment, and a business plan to the deal. The franchisee puts up the money and does all the work. On the negative side, the franchiser gives up some control by not owning each restaurant or store directly. The franchisee gives up her or his ability to make personal decisions because she or he has to obey the rules of the company.
