It's not like in the states where we typically tip between 15 and 20 percent of the total bill. When in France, or in a french territory, I typically tip 5 to 10 percent after rounding the bill up to the next whole euro amount. But, I base this top on the service I received and the attitude of the waiter/waitress. So, if my bill was 52 euros and the service was good I would bump it up to 55 euros. If the staff was outstanding, like it was a few times when we ate at Ocean 82 in Grand Case in the past, I would raise my tip to 10 percent and give them maybe 58 euros. Tipping beyond those amounts is really not necessary. Hope that helps.
