What cultural faux pas should I try to avoid making in Aix-en-Provence?

"When visiting Aix-en-Provence, it's important to remember that the French value their language and may take offense if you don't at least attempt to speak some French. Even a simple "Bonjour" or "Merci" can go a long way. Avoid speaking loudly in public places, as the French generally speak in softer tones and may find loud voices disruptive or disrespectful. In France, it's customary to greet people with a kiss on both cheeks. However, it's best to follow the lead of the locals, as the number of kisses can vary from region to region. In Aix-en-Provence, it's usually three kisses. When dining out, remember that the French take their food very seriously. Avoid asking for substitutions or changes to the menu, as this can be seen as an insult to the chef. Also, it's considered rude to leave food on your plate, so only order what you can finish. In Aix-en-Provence, as in the rest of France, it's considered impolite to rush. Whether you're dining in a restaurant or shopping in a boutique, take your time and enjoy the experience. The French value leisure and relaxation, so try not to be in a hurry. Finally, remember to dress appropriately. The French are known for their fashion sense, and in Aix-en-Provence, people tend to dress more formally than in other parts of the country. Avoid wearing shorts, flip-flops, or other casual attire, especially in more formal settings like restaurants or theaters," remarked another expat in Aix-en-Provence , France.
