Thai people are extremely polite and their behavior is tightly controlled by etiquette, much of it based on their Buddhist religion. It is a non confrontational society, in which public dispute or criticism is to be avoided at all costs. To show anger or impatience or to raise your voice is s sign of weakness and lack of mental control. It is also counter productive, since the Thai who will smile, embarrassed by your outburst of anger or frustration is far less likely to be helpful than if you had kept better control of your emotions.

Revealing clothing, worn by either men or women, is a little disgusting to most Thais. Short shorts, low cut dresses and T-shirts and skimpy bathing suits come into this category. In temples, long trousers or skirts must be worn, and monks should on no account be touched in any way by women. Shoes should always be removed when entering temples and private houses. For this reason, most Thais wear slip-on shoes to avoid constantly tying and untying laces.

The head is the most sacred part of the body, so should not be touched. The feet are the least sacred, so when sitting they should not point at anyone – most Thais sit on the floor with their feet tucked under their bodies behind them. To point, particularly with foot, is extremely insulting.

Avoid touching Thai people, it is too intimate a gesture and an invasion of personal space.

When eating, it is considered very rude to blow your nose or to lick you fingers. The right hand must be used to pick up food eaten with the fingers.

Clothing from the lower parts of the body should never be left anywhere in a high position. This applies particularly to socks and underwear, but also to shorts and skirts. This is the case even when washing and drying clothes. Thais have two clothes lines – a high one for most clothes and a low one for underwear and socks.

Thais do not traditionally shake hand, the wai is the usual greeting. The hands are placed together as in prayer, and raised upwards towards the face, while the head is lowered in a slight bow. The height to which the hands should be raised depends on the status of the person you are waiing. In the case of monks, dignitaries and old people the hands are raised to the bridge of the nose, with equals only as far as the chest. Young people and inferiors are not waid, but nodded slightly to. You will be regarded as a little foolish should you wai to them.

When you consider that shaking hands, and kissing, are perhaps the easiest means of passing germs, the wai, is in fact a suitable greeting.

It is easy, entering a foreign culture for the first time, to make mistakes in etiquette. If you do so, just smile, wai the person you may have offended, and you are forgiven.

Thais are famous for their smiles.  The Thai smile can say many things. Thais smile when they are happy, amused, embarrassed, uncertain, wrong, annoyed or furious. As westerners, we are not generally able to interpret the type of smile we are receiving but be aware that it may not mean what you think it means. 

Shorts are considered improper and low-class attire in Thailand, only acceptable for schoolchildren, street beggars, and common laborers …not wealthy tourists! Except at beach resorts, you should never wear skimpy shorts, halter tops, low-cut blouses, or anything else that will offend the locals. Long slacks and a collared shirt are recommended for men in urban environments. Women should keep well covered. Swim-wear is only acceptable on the beach.

The use of the word ‘heart'( jai ) is very common in the Thai language, here are but a few examples; jai lorn – angry, nam jai – feelings, nork jai – unfaithful ( adulterous ) jai dee – good hearted, jai dum – black hearted, 

Conversely, the foot is considered the lowest and dirtiest part of the body. The worst possible insult to a Thai is to point your unholy foot at his sacred head. Keep your feet under control; fold them underneath when sitting down, don’t point them toward another person, and never place your feet on a coffee table.

The left hand is also unclean and should not be used to eat, receive gifts, or shake hands. Aggressive stances such as crossed arms or waving your arms are also consider boorish.

While Westerners tend to pick up subtleness in tone of voice to indicate someone’s mood, Thais read more into your body language and approach. Emphasis is usually placed on passiveness and although they are used to foreigners being abrupt, it pays to smile constantly and go gently. Eye contact is a common and important method of placing strangers at ease and there is good reason why Thailand is known as ‘the land of smiles’. The Thai are incredibly patient and forgiving in an imperfect society and are happy to accept things as they are. The best you can do as a foreigner is to offer a soft laugh in testing situations, and say ‘mai pen rai’ (never mind) – a frequently used excuse.

The don’ts of everyday Thai social behavior are less clearly defined than those concerning the monarchy or religion, especially in Bangkok where Western customs are widely accepted. However, what is acceptable in Bangkok may not be accepted in the countryside where traditions remain strong and are strictly adhered to.

Below are a few examples of customs to pay attention to while visiting Thailand:

• Thais do not normally shake hands when they greet each other, but instead press the palms of their hands in a prayer-like gesture called a ‘wai’. Generally, a younger person should wai an older person, who will then return it. The Wai can also be used as a means of saying sorry, thank you, or to pay respect. A Thai person will often Wai as he approaches a temple, Buddha image, or other item of religious significance.

  If you are introduced to a Thai and that person Wais to you then you should return the Wai. Generally the younger person will Wai first, but the Wai of a small child is best returned by a big smile. If you receive a thank you Wai from an airline stewardess or after tipping a waitress it is inappropriate to return the Wai, but a smile is always welcome.

• It is considered rude to use your foot for pointing, especially when pointing at a person. Thais regard their head as the highest part of the body and do not approve of touching anyone’s head, even in a friendly gesture. At social gatherings, young Thais go to considerable length to keep their head lower than those of their elders in order to avoid giving the impression of looking down on them. This is not always possible, of course, but it is the effort that counts.

• Public displays of affection between men and women are frowned upon. You may see some young Thai couple holding hands but never kissing in public.

• Losing one’s temper, especially in public, will likely achieve nothing. Thais see such displays as an indication of poor manners. Visitors will have more success in communicating by remaining calm and polite.

• Do not be surprised if you are addressed by your first name, e.g. Mr. Bob or Ms. Mary. Thais refer to one another in this manner, usually with the title “Khun” (i.e. Mr., Mrs., or Ms.).

Someone is angry at you and they smile.
