We were asked at Chefs de France, Concourse Steakhouse, and Sci Fi. The only one that asked about special diets was France. We had great service at all places!
We were asked, which was fine. I have no shame in being on the DDP, we were treated well and food was good, no complaints. I know the staff has to ring the DDP differently from nonDDP, so I figured they were trying to help out the wait staff. I would never think anything suspicious of it.
We were asked at the podium at Kona, Le Cellier, Concourse, and Sci-Fi. Everytime, we had great service (extra special service at Le Cellier where I mentioned I went to University in one CM's hometown - our kids were chosen to be Jr. Chef's - with the head chef coming to our table to help the kids make their own desserts).
We have never had a bad server experience due to the DDP.
