Read and answer the questions below.

Customs and Manners in Foreign Countries

1. You have to shake hands when you're coming or going in Germany, but in Britain you usually only shake hands when you meet someone for the first rime.
2. You have to give your present in public in the Middle East to show it's not a bribe, but it's good manners to give your present in private in Asia.
3. You mustn't give cutlery in Latin America because it suggests that you want to cut off the relationship. You mustn't give food or drink in Saudi Arabia because it suggests you think your hosts aren't offering you enough to eat and drink. You mustn't give a clock in China because the Chinese word for clock is similar to the word for funeral.
4. 'Come any time' means 'I want you to visit me" in India. If you don't suggest a time and arrange a visit immediately, an Indian will think you are refusing the invitation. But if an English person says 'Come any time', they will think you are bad mannered if you start fixing a date.
5. Offices are usually closed on Fridays in Muslim countries.
6. Americans usually mean 'Yes' when they nod their heads. An English person probably just means 'I understand', and an Asian is just showing interest.
7. It's bad manners to discuss business at a social occasion in India.
8. In Thailand you have to shake hands very gently. It's not like America where a weak handshake can indicate a weak character. In Japan you have to bow when you meet someone for the first time but in Thailand you have to put the palms of your hands together in a prayer gesture. And you mustn't touch your head in Thailand. It's bad manners.
9 You must treat your contact's business cards with respect in Japan. You have to study them before you put them away and you mustn't write on them.
10 In an English pub, you have to take your turn to buy a 'round' - a drink for everyone in your group.
