Be respectful of local culture but don't expect that you have to know everything. Most Thais will make allowances for foreigners. Try to learn a few words of the local language. This show's to all your interest in the country and its culture and is considered another demonstration of your cultural sensitivity and good breeding. Foreigners are expected to be punctual, but do not expect Thais to be on time.
Heavy traffic is the most common excuse for tardiness.
First meetings should be held in offices, restaurants, or hotel lobbies. Business cards are always exchanged at the first meeting. Be sure your card indicates your position and responsibility, as Thais are impressed by titles. Begin initial meetings with casual conversation on such topics as your travels, the beauties of Thailand, and your counterpart s overseas experiences. Avoid topics relating to politics, the royal family, and religion.
