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

"When visiting Denarau Island in Fiji, it's important to respect the local customs and traditions. Dress modestly, especially when visiting villages or religious sites. Revealing clothing is considered disrespectful. Always ask for permission before taking photographs of locals, as some Fijians consider it disrespectful to have their picture taken without consent. Avoid touching someone's head, as it is considered a sacred part of the body in Fijian culture. When visiting a village, it is customary to bring a gift of kava, a traditional Fijian drink, for the village chief. Avoid walking through villages at night, as it is considered disrespectful. Do not sit with your feet pointed towards others, as this is considered rude. Avoid raising your voice or showing anger in public, as Fijians value calm and respectful behavior. Do not enter a house or a room before the eldest person. It's a sign of respect to let the eldest go first. Avoid eating or drinking while walking around, as it is considered impolite. Remember to always use your right hand when giving or receiving items, as the left hand is considered unclean. Lastly, respect the environment. Do not litter or damage natural resources. Fijians have a deep respect for nature and expect visitors to do the same," remarked another expat in Denarau Island, Fiji.
