What is the etiquette on tipping in Thailand? What is an ok amount, eg taxis, hotel porters, bars & restaurant?

Thai don't usually tip, but they do expect something from a foreigner. My advise is for taxi is just around off to the nearest 20 baht. Hotel porter again 20 baht unless many bags or heavy lifting then 40 baht. bar not a damn thing, restaurants if a very hi so place they may add in a service charge so don't tip. Many small Thai restaurants owners will keep tips from it help, so I always give it unnoticed to the waitress

Thai own thinking is to show they are not trying to grab the last Baht, they will leave the coins as a tip, unless it is less than 5 Baht, then an insult. 20 to 40 Baht is a typical tip from a Thai who feels service has been nice or extra. Foreigners are messing this system up by throwing 100THB or more down. Thai in some service roles are beginning to expect foreigners to tip for everything. Stop that.

Don't. Tipping marks you as a dumb tourist. Thais don't tip.

Thai;s don't tip, Just leave the coins from your change on the plate. Many times you will get more coins in your change than normal; Taxi's.. I usually round off up and say Kop Khun Kup (Thank you)

Generally little or none, the average thai worker would not expect a tip. Tipping is a western idea. Taxis-10-20baht at most. Your fare will usually be 65-120 baht in Bangkok, again the change. for a 65 baht fare you give him 80 baht, you might give him the 15baht change or less Restaurant-whatever coin change you receive back after paying the bill. Up to you to leave more. Again that's all they expect. Watch out before you leave a tip. Look carefully at the bill. I noticed at K restaurant a "service charge" i.e. cleverly disguised way of tipping which I don't think goes to the order takers nor cooks. Porters, I normally If I have it 10 baht per bag. I bring a big 26 in bag loaded for a week. I normally give 20 baht because Bars-like a restaurant only the coin change Don't feel obligated to tip. The thai earn what they earn. It the farang or foreigners that can taint their view of us good or bad.

You see holiday millionaires in Asia all the time. It was the Asians who coined the phrase about fools and their money. Ever seen Asians tip? I haven't in the 12 years I've lived here. Throwing your money around earns you no respect, it just makes you a target.

Tipping is not a part of Asian culture. We are told to earn money by hard work. Any money that does not involve real hard work and gets as a gift is not considered as hard earned money. There is no fixed rule when it comes to tipping it is all about your generosity. Thai taxi drivers already charge extra 100 THB since they do not run a meter so it does not make sense to tip them. Same with tuk tuks/auto rickshaws. As for hotel porters they deserve a tip. They carry your luggage down the stairs and put them in a taxi cab. Starting point should be 100THB that's not too much money. When upon leaving my hotel I tipped 100 THB to a security guard since he brought my suitcase downstairs from my room. He kept staring at the note I felt like he did not want to take it but after a few seconds of rumination he took it gently. Thais deserve a tip because their kindness and politeness is unmatchable. What is so commendable is they never let their misery shown on you. They will have you believe that their life is great and full of smiles. 50-100 THB should be your starting point. Also, average Thais earn meager salary so their tipping parameter should be low, obviously. I am sure, rich/well to do Thais tip more than that of 40THB for sure.

no tipping is expected in thailand. they even think you are weird if you say "thank you" to waitresses, porters and such.

Thai people are so lovely I always want to tip them. They go out of their way to provide service of all types, but my Thai friend would always stop me. Now I am an Australian so we don't tip often and certainly only tip for extraordinary service. So basically you don't tip unless you are staying in a 5 star hotel.
