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

"When visiting Bali, it is important to dress modestly, especially when visiting temples or attending ceremonies. Avoid touching someone's head, as it is considered the most sacred part of the body. Do not use your left hand to touch someone or give or receive something, as it is considered impure. Be mindful of your feet, as pointing them at someone or stepping over someone is considered disrespectful. Avoid public displays of affection, as they are frowned upon in Balinese culture. Be respectful of the local customs and traditions, and do not interrupt or walk in front of a religious procession. Do not enter a temple if you are menstruating, have an open wound, or are in mourning, as it is considered impure. Be cautious when taking photographs, and always ask for permission before taking pictures of people or religious ceremonies. Do not climb on sacred monuments or structures. Finally, be patient and polite when bargaining at markets, and avoid getting angry or raising your voice, as it is considered impolite," said another expat in Bali, Indonesia.
