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

"In Avignon, it is considered rude to not greet shopkeepers, waiters, or hotel staff when entering or leaving their establishments. Always say "Bonjour" (Good day) or "Bonsoir" (Good evening) and "Au revoir" (Goodbye) when leaving. Avoid speaking loudly in public places as the French value discretion and respect for personal space. It's considered impolite to eat while walking or to consume food in places that are not designated for eating, such as in stores or on public transportation. In France, it's customary to kiss on both cheeks when greeting friends, but it's best to follow the other person's lead. Don't initiate this form of greeting with strangers or casual acquaintances. It's considered rude to ask personal questions, especially about money or salary. The French value their privacy and don't typically discuss personal matters with people they don't know well. Avoid criticizing France or comparing it unfavorably to other countries. The French are proud of their culture and heritage and may take offense to negative comments. In restaurants, it's considered impolite to ask for a doggy bag or to take leftovers home. This practice is not common in France. Remember to dress appropriately when visiting religious sites. Cover your shoulders and avoid wearing shorts or short skirts. Finally, always try to speak some French, even if it's just a few phrases. The French appreciate when visitors make an effort to speak their language," remarked another expat in Avignon, France.
