Friendliness and hospitality are characteristic of the people of Thailand
However, defiant and arrogant behavior of tourists offends the pride of the Thais who preserve their traditions; it is considered extremely inappropriate to lose patience and show displeasure. People in Thailand smile even when they feel down, they are used to hiding their fears and emotions from strangers.
The royal house is held in especially deep respect and reverence; criticism of it is unacceptable under any circumstances. Objects and pictures depicting the king are placed in the most honorable places. The same applies to images of Buddha as symbols of faith.
Buddhism is deeply rooted in the daily life of the Thai people. Early in the morning, monks wrapped in orange robes appear on the streets to receive offerings from believers. Donors thank the monks for accepting their gifts, thereby giving them the opportunity to perform a worthy deed. Women are not allowed to touch a monk.
As for general rules of behavior. Public displays of affection are taboo in this country. The head is the most sacred part of the body, and it is impermissible to touch an adult's head. It is generally not acceptable to touch a person, pat them on the shoulder. Likewise, one should never point one's feet in the direction of another person. It is also considered impolite to stand over someone. Therefore, if you pass by a seated person, you should symbolically bow your head slightly.
Particularly big issues are associated with the correct use of the "wai" – the traditional Thai greeting (the height of the hands corresponds to the social status of the person being greeted). A slightly bowed head – but in no case a handshake – will be perceived by Thais as a form of greeting from a foreign guest.
Carelessness in dress, especially when visiting a temple or royal palace, will be viewed with disapproval. Women should have a closed dress with sleeves or a shawl for such occasions. Shoes must be removed when entering a temple.
Those who, during their travels, want not only to admire the country's attractions but also to try to understand Thailand and the Thai people, should pay close attention to everything mentioned above.
