Below is a link to Fodors and French service / tipping protocol

Dutch side, check the bill to see if service is included and tip accordingly or not.

The fly in the ointment is when a resto on the Fr side puts "service not included" on the bill and the server echo's that comment when presenting the bill. I pay the bill, leave a small tip if the service was good and don't return to that resto as I won't support that practice of preying on a tourist
