Our family of 3 has some private day tours booked for Thailand and Myanmar. How much should we tip the guide for the day? how much for the. Tipping. Tipping is NOT customary in Thailand, there is absolutely NO mandatory requirement to tip anyone, but small gratuities for great service are very much. Wondering how much to tip in Thailand? Here are some general guidelines on what to leave service people in restaurants, hotels and beyond. The bill isn't left on the table in a Mastercard branded wallet, as it would be at a mall restaurant; the deal mahjong fussball usually done verbally and any due change summoned from the cook's apron. It's simply not the nature of such places. I've read a few threads on the web over the years where some foreigners curse others for tipping too. On the next trip, I stayed at a different hotel, which is part of the same hotel family. It just ruins their morality.
