When I go to a resaurant on land I tip 15% if service were marginal and typically tip 20% which is the norm in these parts.
Last night for instance....dinner at a local bbq place was $46.39 and I tipped $10 dollars because service was great. It would have been a larger tip if it were a fancy steak house or whatever.
I'll tell you they didn't work near as hard as any waiter I've had in a cruise ship dining room!
Not to mention they work breakfast and lunch as well.
I for one don't mind the auto tip. Just knowing I have the option to cancel through the Purser's desk if service is rotten is comforting. It would have to be pretty bad for me to cancel it.
