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

"In Ranong, it is considered disrespectful to touch someone's head as it is regarded as the most sacred part of the body. Avoid pointing your feet at people or religious objects, as feet are considered the lowest and dirtiest part of the body. It's also considered rude to step over someone's legs or feet, so always walk around. Public displays of affection are generally frowned upon, especially in more traditional or rural areas like Ranong. It's best to keep affectionate gestures private. When visiting temples or religious sites, dress modestly. Women should cover their shoulders and knees, and men should also dress respectfully. Remove your shoes before entering someone's home or a temple. Avoid showing anger or frustration in public. The Thai people value a calm and cool demeanor, and public outbursts can be seen as embarrassing and disrespectful. Do not disrespect the Thai Royal Family. This is a serious offense in Thailand, punishable by law. Avoid making negative comments about the country or its people. Thais are very proud of their country and culture, and such comments can be seen as disrespectful. When eating, use a spoon as your main utensil. The fork is typically used to push food onto the spoon. Also, leave a little bit of food on your plate after a meal to show that you are full and satisfied. Lastly, always return a "wai" (a traditional Thai greeting involving a slight bow with palms pressed together). Not returning a "wai" is considered impolite," remarked another expat in Ranong, Thailand.
