Oh, that's fantastic. If I had been there in line behind you, I would have bought you dinner to thank you.
I've noticed that behavior a few times myself. Where's the supervision and local management to clamp down on that stuff? It's just unprofessional. If the Imagineers who designed and built these rides, many of which were supervised by Walt himself, had wanted a vamping lounge singer on the unload dock they would have added an animatronic to perform that role.
But why is that even okay for these CM's? Where's the supervision to clamp down on it and keep them professional? They are not the star of the show, they are merely the polite and efficient operator who keeps the real show running.
