Most senior businesspeople in large or international companies will speak English, but it is not common in smaller companies. It is essential to make appointments for business meetings and to exchange business cards. Punctuality is also very important (although the visitor is quite often likely to be kept waiting after arrival), so the Bangkok traffic must be taken into consideration when going to appointments. Thai hosts are quite likely to give small gifts to visitors, so it is a good idea to reciprocate with a typical national gift of one's own. Visitors should never get angry or raise their voice if things are not going according to plan, as this will mean a loss of face on both sides. Much more progress will be made by remaining calm.

Meetings often take place over lunch and these are generally held in a Thai restaurant. Thai businesspeople are quite formal in their dress but, because of the extreme heat, it is quite acceptable and practical to dispense with the wearing of a suit jacket. Office hours are usually Monday to Friday 0800-1700. There is a large expat community in Bangkok, as well as a big after-work drinking scene.
