Language
Thai is the country's official language and is spoken by the majority of individuals. The Thai language is sometimes referred to as the Siamese language.
Good Manners
Do dress properly- Make sure to dress respectively while wandering around the country, especially if you decide to visit Thai temples. Shoulders and knees must be covered for both sexes.
Do take off your shoes- In Thailand, feet are considered dirty. You should always remove your shoes before entering a temple or a person’s home. Some shops may even ask for you to leave your footwear at the door.
Don’t touch a person’s head- In Thai culture, the head is the most important part of the body, and it’s therefore considered extremely rude to touch the top of a person, or figurative statue – especially if a representation of the Buddha.
Do address people by their first name- Often, the title Khun is added before the first name. This is similar to Mr. or Mrs., and is used for both men and women, regardless of marital status. Family names are typically only used in formal settings.
Do show respect for the royal family- Stop to pay respect during the National Anthem, and avoid making any negative comments about the king.
Alcohol
The drinking age in Thailand is 20, and it's in the interest of bar owners to enforce this, as establishments do occasionally get raided by police looking for underage drinkers and patrons under the influence of illegal substances.
The sale of alcohol is banned from 2 pm to 5 pm, and from 12 am to 11am. It's also banned on some religious festivals.
