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

"When visiting Marseille, it's important to avoid making the cultural faux pas of not greeting people properly. Always say "Bonjour" (Good day) or "Bonsoir" (Good evening) when entering shops, restaurants, or when addressing someone. Avoid speaking loudly in public places. The French value discretion and may find loud conversations or behavior to be disrespectful. Don't rush your meals. In France, dining is considered an experience to be savored, not rushed. Take your time and enjoy your food. Avoid discussing money or asking about someone's income. This is considered impolite and too personal. Don't expect shops, restaurants, or attractions to be open all day. Many businesses in France close for a few hours in the afternoon. Avoid wearing overly casual clothing, especially in more formal settings. The French take pride in their appearance and may view sloppy attire as disrespectful. Don't assume everyone speaks English. While many people in Marseille do speak English, it's polite to ask if they do before starting a conversation. Avoid being overly friendly or familiar with people you've just met. The French tend to be more reserved and may find this off-putting. Don't forget to say "please" ("s'il vous plaît") and "thank you" ("merci"). Good manners are highly valued in French culture. Avoid criticizing France or comparing it unfavorably to your home country. This is considered rude and disrespectful," remarked another expat who made the move to Marseille, France.
