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

"In Al Qunfudhah, it is important to respect the local customs and traditions. Avoid public displays of affection, as they are considered inappropriate. Dress modestly, covering your arms and legs, and women should also cover their hair. Do not consume alcohol or pork, as they are forbidden in Islam. Avoid discussing sensitive topics such as religion and politics. Do not take photographs of people without their permission, especially women. During the holy month of Ramadan, do not eat, drink, or smoke in public during daylight hours. Always use your right hand for eating and greeting, as the left hand is considered unclean. Do not refuse an invitation to a Saudi's home, as it is considered a great honor. Always remove your shoes before entering a Saudi home," mentioned another expat when asked about moving to Al Qunfudhah, Saudi Arabia.
