It is considered very impolite to start speaking to anyone providing a service – such as a hotel receptionist, waiter or a shop assistant – without greeting them first. Bonjour (hello) is sufficient. If you are traveling with a group of people, you should greet each person individually on arriving and before departing. Table manners are particularly important, and you should take your time when eating and drinking. Being overly loud or brash is also a no-no. Drunkenness is not tolerated.
