Well, since I work in the Emporium, I always forget about this recent happening:
If you look up in the Emporium on Main Street USA, you might see a whole bunch of AA's looking around. They are all around the store and they are not very animatronic. I would venture to say they have been there since day 1 without any change. Anyways, one of AA scenes with a barber and a kid stoppped working at least 3 weeks ago. The Barber actually fell down and doesn't work anymore. From far away, you can see his arm stick out and the boy looks around at nothing.
Sadly, this is a poor example of Disney not keeping everything in working order. I figured Al might like this to show how keeping things clean and new doesn't always happen. Those of you out every week in the park with a camera, snap a photo. I never bring mine, but I just wanted to give a heads up to those who love those AA's.
