What cultural faux pas should I try to avoid making in Gros-Morne?

"When visiting Gros-Morne, it's important to respect the local customs and traditions. Avoid wearing revealing clothing, especially in religious places, as it is considered disrespectful. It's also considered rude to speak loudly in public places, so try to keep your voice down. Do not litter or disrespect the environment, as Martinique is known for its beautiful natural landscapes and locals take pride in preserving it. Always ask for permission before taking photos of locals, as it is considered impolite to do so without consent. Avoid discussing sensitive topics such as politics and religion, as these can lead to heated debates. It's also considered impolite to interrupt someone while they are speaking, so wait for your turn to speak. When dining, it's customary to finish all the food on your plate, as leaving food is seen as wasteful. Also, tipping is not customary in Martinique, so don't feel obligated to leave a tip after a meal. Lastly, punctuality is not highly valued in Martinique, so don't be surprised if events or meetings start later than scheduled. However, as a visitor, it's best to arrive on time to show respect," mentioned another expat when asked about moving to Gros-Morne, Martinique.
