Here are 30 of the most common mistakes that virtually every newcomer in France (including us at The Local) makes when first arriving in France. In France, you’ll get a weird look and possibly an offended Frenchie if you don’t ask first. Saying “Bonjour” to the same person more than once in the same day is seen as rude, like you’ve forgotten you already greeted them. A French person will take advantage of it and cut right in there, so just get cozy with the person in front of you if you want to keep your spot. Saying “Bonjour” twice to the same person in the same day.
