It is also the custom of Thai people to use the word "farang" instead of the word "foreigner". Not all foreigners feel the same about the word "farang". Some thing it's funny, and like the word. Others think it's rude, and get angry if you use it to talk about foreigners or their culture. This is because in English it's not polite to use a special word about people just because of the color of their skins.
