Follow household cues
Remove shoes when hosts do or when they indicate, bring a modest gift when appropriate and avoid entering private areas without invitation. Compliment hospitality without inspecting sacred or family objects. If food is offered, communicate dietary limits politely rather than making the host guess.
Shared meals are collaborative
Thai meals often place several dishes in the centre with individual rice. Take modest portions, use the serving utensil and let the group set the pace. Confirm allergies carefully because sauces, stocks and garnishes may contain ingredients not obvious from the dish name.
Markets reward polite clarity
Bargaining is context-dependent, not a requirement everywhere. Ask the price, make a reasonable counter-offer where negotiation is normal and walk away politely if it does not suit. Do not handle food, antiques or religious objects roughly, and seek permission before photographing a vendor closely.
Gratitude matters more than performance
Tipping practices vary by setting; check whether service is included and reward good service without creating pressure. A sincere thank-you, patience and returning custom can matter as much as a formal gesture. Avoid using cultural stereotypes as jokes or expecting people to perform tradition on demand.
