When I first started my CP, I had driven to the main gates at MK and asked a CM how to get to Disney University. He was nice until I asked for directions, then he was SO RUDE to me! As soon as he saw I was a cast member like him any trace of politeness vanished.
Every so often, on my way to work, I'd drive through the main gates at the MK just for a change of pace. I had that guy multiple times and he was incredibly rude EVERY TIME I came through. He took the wind right out of my sails...honestly the last thing I needed before a 10 hour shift was a rude cast member who was on the clock!
When my family was visiting, we ended up in his line at the gate and he was just sweet as pie to my parents. I was in the backseat so he didn't see me.
I should have reported the guy. I regret not doing so.
I admit, one day I was working the topping bar at Cosmic's and the Tangled meet and greet was going on across the street. I commented to another CM about how hot her wig must have been when she was standing in the sun.
There were no guests at the time, but I was HORRIFIED I had made such a comment. I immediately corrected myself to say 'but I'm sure she's used to having such beautiful natural hair so of course the heat won't bother her'
When I was working there, the biggest things that ruined the magic daily were seeing the CM's smoking everywhere backstage and how snotty some of the princesses were when they were off duty.
