Explanation
In Thailand, tipping is not traditionally expected at restaurants, especially in local eateries, as service is considered part of the hospitality. However, in tourist-heavy areas or upscale establishments, a small tip (around 10% or rounding up) is becoming more common and is seen as a gesture of appreciation. Leaving no tip is never considered rude, but a small tip can enhance the dining experience for both parties.
Local Tip
If you choose to tip, leave small coins or a 20-50 baht note on the table; avoid tipping with coins alone in fine dining as it may be seen as less respectful.
How it compares elsewhere
Tipping is considered insulting as service is included; leaving money can cause confusion or offense.
Tipping 15-20% is standard and expected for good service; not tipping is seen as rude.
Service charge is included by law, but leaving small change is polite; overtipping is unnecessary.
