Greetings When entering or leaving a shop, it's polite to say bonjour and au revoir. When greeting friends, it's usual to give a kiss on both cheeks and ask Comment ça va? (How are you?)
Conversation Use vous (you) when speaking to people you don't know well, or who are older than you; use tu (also you) with friends, family and children.
Asking for help Say excusez-moi (excuse me) to attract attention; say pardon (sorry) to apologise.
Religious buildings Dress modestly and be respectful when visiting.
Eating & drinking When dining in a French home, wait for your host to start first. Always clear the plate. When you're finished, line up your fork and knife on top of your plate towards the right.
Waiters Never, ever call waiters garçon – use Monsieur (Mr), Mademoiselle (Miss) or Madame (Mrs), or attract their attention by saying s'il vous plaît (please).
