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

"When visiting Bordeaux, it's important to avoid making the cultural faux pas of not greeting people properly. Always say "Bonjour" during the day or "Bonsoir" in the evening when entering shops, restaurants, or when addressing someone for the first time. Avoid speaking loudly in public places as the French value discretion and respect for personal space. They also appreciate quiet conversations, so try to keep your voice down. In Bordeaux, as in the rest of France, it's considered rude to eat or drink while walking on the street. Take the time to sit down at a café or restaurant to enjoy your meal or drink. Don't rush your meals. In France, dining is considered an experience to be savored, not rushed. Take your time and enjoy the food and the company. Avoid discussing money or personal wealth. The French consider this topic to be in poor taste and it's generally avoided in casual conversation. Don't assume everyone speaks English. While many people in Bordeaux do speak English, it's polite to ask if they do before starting a conversation in English. Avoid wearing overly casual clothing, especially in upscale restaurants or wine tasting venues. The French take pride in their appearance and dressing well is considered a sign of respect. Lastly, don't forget to say "please" ("s'il vous plaît") and "thank you" ("merci"). Good manners are highly valued in French culture," remarked another expat in Bordeaux, France.
