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

"When visiting La Rochelle, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, always greet people with a polite "Bonjour" during the day or "Bonsoir" in the evening. Not doing so can be considered rude. Avoid speaking loudly in public places as French people value discretion and may find it disrespectful. When dining, remember that the French take their food seriously. Don't rush your meal, take your time to enjoy it. Also, it's considered impolite to eat while walking on the street. In France, tipping is not mandatory but it's appreciated. If you're satisfied with the service, leave a small tip. Don't assume everyone speaks English. Although many people in La Rochelle do speak English, it's polite to ask first, "Parlez-vous anglais?" Avoid discussing sensitive topics like politics and religion unless you know the person well. Lastly, remember that the French value their personal space. Avoid touching, hugging, or standing too close to someone unless you know them well. A simple handshake or a kiss on the cheek is the common form of greeting," said another expat in La Rochelle, France.
