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

"In Kep, it's important to respect the local customs and traditions to avoid any cultural faux pas. Dress modestly, especially when visiting religious sites. Revealing clothing is considered disrespectful. Avoid touching someone's head or pointing your feet at someone, as the head is considered sacred and the feet are considered the lowest and dirtiest part of the body in Cambodian culture. Public displays of affection are generally frowned upon, especially between men and women. It's best to refrain from hugging, kissing, or holding hands in public. When visiting temples or other religious sites, always remove your shoes before entering. It's also respectful to leave a small donation for the monks. Never use your left hand to give or receive something, as it is considered impolite. Always use your right hand or both hands. Avoid discussing politics and the country's past, especially the Khmer Rouge period, as these topics can be sensitive. Do not take photos of people without their permission, especially monks and children. It's considered disrespectful and invasive. Avoid raising your voice or showing anger in public. Cambodians value calm and composed behavior. Lastly, be respectful of the environment. Do not litter or damage natural resources, especially in Kep National Park," mentioned another expat when asked about moving to Cambodia.
