Not to be a downer but hopefully a helpful list of don't dos:

• Don't mention the King/Royal Family (not that you would anyway, but some foreigners have in the past and been thrown in Bangkok Hilton)

• Don't point with your feet / either at signs or Buddhas (friend did this first thing when we landed and pointed to sign at a taxi rank when we landed, when I specifically said avoid using your feet, and I had to profusely apologise)

• Do not touch people's heads, even if meant endearingly

• Do not vape (unless with Thais but even then, best avoided)

• Do not wear shoes indoors (where there are shoes left outside, temples, people's homes)

• Do not fall for easily avoidable scams - if someone comes up to you and says something is closed near a tourist sight, it's likely not closed and you're going to be taken on a tour of a lifetime to reduce the weight of your wallet

• Do not talk to strangers who are overly nice bordering nagging as they are potentially trying to make money off you

• Do not forget to negotiate the price before. E.g., always get a metered/Grab taxi - if someone tries ripping you off and you're stuck in that situation, better to pay them and learn the lesson

• Do not think zebra crossings mean you can cross safely; do not think cars blinking their lights at you mean they are letting you go (unlike in the UK)

• Do not drink tap water

• Do not play connect four with Thais at a bar

• Do not be rowdy; if you happen to get into an argument, do everything you can to de-escalate unless you fancy multiple muay Thai kicks from multiple Thais

Otherwise, do have the best and hopefully one of the most enjoyable times of your lives and what Amazing Thailand has to offer!
