Monarchy & Buddhism
The Thai monarchy commands genuine reverence — do not make critical or satirical comments about the royal family, even in private conversation. Lèse-majesté laws are actively enforced and have resulted in significant prison sentences for foreigners. Similarly, treat Buddhist temples and monks with visible respect: shoulders and knees covered, shoes removed at temple entrances, feet never pointing toward Buddha images.
Temple behaviour
When visiting temples, remove shoes at all marked points, dress modestly (sarongs and cover-ups available to borrow at major sites), speak quietly and do not touch Buddha images. Women should not touch or hand items directly to monks.
Social customs
The traditional greeting is the wai — palms pressed together at chest height with a slight bow. Returning a wai is polite; you need not initiate a wai to strangers. The concept of sanuk (fun/enjoyment) is genuinely important — maintaining a lighthearted approach in most situations is culturally appropriate and practically effective.
Tipping
Tipping is appreciated but not the compulsory norm it is in some Western countries. Approximately 20–40 baht per person at restaurant tables is the local guideline; rounding up taxi fares is standard; nothing is expected at street food stalls. At luxury hotels, 100 baht per bag is appropriate for porters.
Bargaining
Bargaining is normal and expected in markets (Chatuchak, Pratunam, night markets) and with tuk-tuks. It is not appropriate in shopping malls, chain restaurants or metered taxis. Start at around 50–60% of the asking price and negotiate from there.
