What else should be avoided in Thailand
Generally you should never touch a Thai’s head, this also applies for children. Following the Thai belief the head is the domicile of the soul and the spirit. Is it touched by mistake you should apologise politely.
Feet in Thailand are said to be unclean thence you should not sit on the floor with stretched legs as the feet could point at other people.
Never point at people with the index finger in Thailand but with the chin in the appropriate direction.
