It's things like this that really do make someone's day at the World. Last year during one of my trips to WDW, I ran into an amazing cast member. Come to find out she was a trainer in the Magic Kingdom. We had a great discussion, and I told her that the thing Cast Members may not realize is that they make or break our experience.
I explained that without the individuals who truly "make the magic" happen, the Disney Parks would be just like all the rest of the theme parks. I also told her that the atmosphere makes their work more difficult but more important than anywhere else because when you go anywhere other than Disney World, you tend to remember the one great thing that someone does for you because it sticks out from the "norm." But when you go to Disney World, it seems like you tend to remember the one bad thing that happened because bad interactions are not the norm.
Cast Members really do a lot for the guests of Disney's Parks, and I know they are one of the reasons I keep going back. Great customer service is like a drug.
