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

"In Al Ula, it is important to respect the local customs and traditions. Dress modestly, covering your arms and legs, and women should also cover their hair. Avoid public displays of affection, as they are considered inappropriate. Do not consume alcohol or pork, as they are forbidden in Islam. Always use your right hand for eating and greeting, as the left hand is considered unclean. Do not take photographs of people without their permission, especially women. Avoid discussing sensitive topics such as politics, religion, and sex. During the holy month of Ramadan, do not eat, drink, or smoke in public during daylight hours. Always ask permission before entering a mosque, and remove your shoes before entering. Do not bring any items that are considered haram or forbidden in Islam, such as alcohol, pork, or items related to other religions," remarked another expat in Al Ula, Saudi Arabia.
