　　“Tipping” is always a difficult business. You do not want to give too much little, or tip the wrong person.

　　In Britain or America, people usually tip waiters in restaurant, porters, taxi drivers and hairdressers. They do not tip people in offices, cinemas, garages, or airports.

　　Do you invite your friends to the restaurant? Then you pay the bill. Does your friend invite you? Your friend pays. If there are men and women in the party, men usually pay.

　　These days men and women are equal in many ways. If you work in Britain or America, your boss could be a man or a woman. There are increasing numbers of women in important positions in politics, law, medicine and in the business world.

　　But it is still polite for a man to open doors for women and to ask them to go first. And it is polite for men to stand up when they are introduced to women. On informal occasions, of course, everyone is more relaxed.
