The most frequent question I am asked about dining in France is "What about tipping?"
Here are the basics:
You are not required to tip. A 15% service fee is automatically included in all bars, cafés, and restaurants. Servers in France do not live off of tips. They get paid vacations, health care, and living wages.
A service charge is almost always added to your bill. Depending on the service, it’s sometimes appropriate to leave an additional 5 to 10%. The menu will usually note that service is included (service compris). Sometimes this is abbreviated with the letters s.c. The letters s.n.c. stand for service non compris; this means that the service is not included in the price, and you must leave a tip. You’ll sometimes find couvert or cover charge on your menu (a small charge just for placing your butt at the table).
