I'm not necessarily agreed with the notion that restaurants may want to "get a little out of Americans"... maybe in some touristy hell-trap... but any restaurant of quality deserves a little extra... the French regulations say that you do not have to pay for service, but this doesn't mean that the waitstaff is getting anything out of it... As for tipping in a Michelin starred restaurant, in my opinion, it's a sacrelage not to! Anyone leaving such establishments, tasting the art of gastronomy, taking part in all these places have to offer, and then leaving without expressing their gratitude would come off as a "plouk"..
