When entering a store or restaurant, always say “Bonjour Madame” or “Bonjour Monsieur.” Don’t just barge in and ask for information. If you have a question, it’s polite to begin with “S’il vous plait,” (Please). When you call the waiter or waitress in a restaurant, say, “S’il vous plait Monsieur/ Madame.” If you enter a room of strangers, say, “Bonjour Messieurs-dames.”
