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

"In Kratie, it is considered disrespectful to touch someone's head, as it is regarded as the highest part of the body and therefore sacred. Avoid showing the soles of your feet towards people or religious artifacts, as feet are considered the lowest and dirtiest part of the body. Dress modestly, especially when visiting religious sites, as revealing clothing is seen as disrespectful. Avoid raising your voice or showing anger in public, as Cambodians value maintaining harmony and face. It's also important not to point with your finger, but instead use your whole hand with the palm facing down. Public displays of affection are generally frowned upon, especially between men and women. It's also considered impolite to pass something with your left hand, as it is traditionally seen as the 'dirty' hand. When eating, leave some food on your plate to indicate that you are full; finishing all your food implies that you are still hungry and the host did not provide enough. Lastly, be respectful of the country's tragic history. Many Cambodians have been personally affected by the Khmer Rouge regime, so avoid bringing up the topic unless it's brought up by locals," remarked another expat who made the move to Kratie, Cambodia.
