听力原文： Americans are big tippers. Generally the custom is more common in a large city than in a small town. Customers are expected to give a tip or small amount of money, whenever services are performed. A tip is expected by the porter who carries your baggage, by taxi drivers and by those who serve you in hotels and restaurants. For example, in hotels it is customary to give a tip to the porter who carries your suitcase and shows you to your room. In this case, 50 cents for each bag is satisfactory; in restaurants you generally leave about 15 percent of the bill on the table as a tip for the person who has served you. Tipping became common in England by the middle of the eighteenth century. Because this practice is not suitable to a country without an established serving class, it did not catch on in America until after the Civil War, when the Southern former slave owners suddenly found themselves having to pay the service and when the rich Northern industrialists adopted this Old World practice as a means to show off their fortune. By the mm of the century the custom had been an American one.
