What cultural faux pas should I try to avoid making in Saint-Joseph?

"In Saint-Joseph, it's important to respect the local customs and traditions. Avoid wearing revealing clothing, especially in religious places, as it is considered disrespectful. Always greet people with a polite "Bonjour" or "Bonsoir" before starting a conversation. It's considered rude to not greet someone before speaking to them. Avoid discussing sensitive topics such as politics and religion unless you are very familiar with the person you are talking to. It's also considered impolite to interrupt someone while they are speaking. In Martinique, punctuality is not as strictly observed as in some other cultures. However, it's still important to be on time for formal occasions or business meetings. When dining, it's customary to finish everything on your plate as leaving food can be seen as wasteful or an indication that you didn't enjoy the meal. It's also important to respect the local environment. Littering is frowned upon and could even result in fines. Lastly, remember that Martinique is a French territory, so the locals appreciate if you make an effort to speak French, even if it's just a few basic phrases," mentioned another expat when asked about moving to Saint-Joseph, Martinique.
