Personaly I don't think that bad service has to do with the
DDP in 2007 (and before) or the auto gratuity with DDE and parties of 6 and more. I think that some servers just aren't as good as others.
That being said - we had bad service at:
Kona Cafe - Waitress spent our entire meal chatting with the table behind us about 'back home' as they were all from the same state. We had to chase her down for refills, the check and everything.
Les Chefs de France - rude service from the man who seated us and refused to bring a new high chair as ours was broken to our server who treated us rudely, was slow, didn't get refills and was just unpleasant.
WCC - Our server was invisible here
Chef Mickey's - Another case here servers are given an invisibility cloak. No refills on drinks without asking, dirty plates piled up. Not just for one meal - for both of our meals here, though our breakfast server was slightly better than our dinner server.
Capt'n Jack's - Had to order our entire meal when we sat down, server rushed us through the first half of the meal. When she brought the check she complained about the DDP and how she wouldn't get the proper tips in 2008. How she couldn't afford to work there and live beginning in 2008 and how cheap people are when tipping - that nobody would tip $40 on a $200 bill, and the change of teh DDP would be the end of good service in Disney.
Boma - slow and invisible server fore both breakfast and for dinner. one time on DDP and another with a small group so no auto gratuity.
Crystal Palace Dinner - rude male server, Crystal Palace Lunch - AMAZINGLY wonderful female server.
(Because I feel bad - we had good to great service at Victoria & Albert's, LeCellier twice, Mama Melrose - twice for dinner, 50's PTC, Liberty Tree Tavern, Narcoosee's, Jiko - twice for dinner, and Beaches and Cream as well as our great server from Crystal Palace for Lunch)
