Americans feel that the first rule of being a polite guest is to be on time. If a person is invited to dinner at 6: 30, the hostess expects him to be there at 6: 30 or not more than a few minutes after. Because she usually does her own cooking, she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come. If he is late, the food will not be so good, and the hostess will be disappointed. When the guest can not come on time, he calls his host or hostess on the telephone, gives the reason, and tells at what time he thinks he can come. As guests continue to arrive, the men in the group stand when a woman enters and remain standing until she found a chair. A man always rises when he is being introduced to a woman. A woman does not rise when she is being introduced either to a man or a woman unless the woman is much older. When the guests sit down at a dinner table, it is customary for the men to help the ladies by pushing their chairs under them. Even an American may be confused by the number of knives, forks, and spoons besides his plate when he sits down to a formal dinner. The rule is simple, however: use them in the order in which they lie, beginning from the outside. Or watch the hostess and do what she does. The small fork on the outside on the left is for salad, which is often served with the soup. The spoon on butter spreader, on a small bread-and-butter plate at the left. As the bread is passed, each quest puts his piece on the bread-and-butter plate. 1. At formal American dinner, the knives, forks, and spoons besides the plate are placed in a certain order. A.
