What cultural faux pas should I try to avoid making in Khao Lak?

"When visiting Khao Lak, it is important to avoid touching someone's head, as it is considered the most sacred part of the body. Be respectful of the local customs and dress modestly, especially when visiting temples or religious sites. Remove your shoes before entering someone's home or a temple. Avoid pointing your feet at people or religious images, as feet are considered the lowest and dirtiest part of the body. Do not show public displays of affection, as it is considered impolite and disrespectful. Be cautious when discussing the Thai royal family, as any negative comments or disrespect can lead to severe consequences. Avoid raising your voice or losing your temper, as Thais value calmness and politeness. Lastly, be mindful of local customs and traditions, and always show respect to the people and their culture," mentioned another expat when asked about moving to Khao Lak, Thailand.
