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

"When visiting Sihanoukville, it's important to respect the local customs and traditions to avoid causing offense. Dress modestly, especially when visiting religious sites, as revealing clothing is considered disrespectful. Avoid touching someone's head or pointing your feet at someone, as these are considered rude gestures in Cambodian culture. It's also considered impolite to touch or move a monk's robe, even if it's in your way. If you're invited to a Cambodian home, remember to remove your shoes before entering. When eating, use your right hand as the left hand is considered unclean. Avoid raising your voice or showing anger in public, as Cambodians value maintaining harmony and face. Do not take photographs of people without their permission, especially monks and children. It's also important to be respectful when discussing the Khmer Rouge period, as it's a sensitive topic for many Cambodians. Avoid giving money to child beggars, as it encourages a cycle of dependency and often supports exploitative practices. Instead, consider donating to a reputable local charity. Lastly, be mindful of the environment and avoid littering, especially on the beautiful beaches of Sihanoukville," said another expat in Sihanoukville, Cambodia.
