Do Return a wai greeting. Bowing in Thailand is called the wai (pronounced as ‘why’). It’s the traditional way Thais greet one another and say hello. The wai is not only used to greet people; it is also used to apologise, thank someone or say goodbye.
Do use a spoon. The proper way to eat in Thailand is with a spoon and fork. The spoon should be in the right hand and the fork in the left. The fork is only used to scoop the food onto the spoon; it should never enter your mouth.
Don’t place your feet on the table while sitting, don’t point to anything with your feet and don’t touch anybody with your feet.
Don’t disrespect the Royal Family. The Thai people have a deep reverence for their king and the royal family. Insulting, disrespecting or talking ill of the king or images of the king can land you a one-way ticket to prison.
