Otherwise, you’ll end up in a right mess! 小题2:________ Let’s have a look: Don’t talk about money: British people hate talking about money and it is considered rude to do so. 小题3:_______ Afternoon Tea: The traditional view of the British sitting down for an afternoon tea is wrong. 小题4:_______ Give tips(小费): The British prefer a quiet “thank you” gift for good service. In fact, many British waiters will not make a fuss (大惊小怪) if you decide not to tip at all. 小题5:________ The British are not like Frenchmen. When Frenchmen meet each other, they often give a kiss. However, many British people prefer a handshake or a pat (拍打) on the back to say “hello”. Conversation tips: If you want to be friendly, end a sentence with the word “mate”.
