Maybe it is just the stress of preparing everything for the 21st!
Nope, the servers (Restaurant Division) have NOTHING nada zip zilch to do with the theming or putting up decorations or anything. They are just bitter people who have been working there forever (Union's can be bad) who don't care and make good money because the food is expensive and people always want to eat there. I had lunch there about a year ago and it was horrendious service, really really bad.
Sorry to burst your bubble.
