For me, common courtesy is the best way to go. When something 'bad' happens (such as being able to get a great FP+ spot for the afternoon parade on June 1 only to have the parade cancelled 5 mins before it should have started) I try not to take it out on the CMs. They didn't cause the issue. I try to be pleasant and chatty....it's always fun to chat with CMs. Speaking of Parade Audience Control....my dd and I were in MK awhile ago. We were waiting for the afternoon parade to start. We were in FrontierLand. Well, this family came up and took up spots close to us. About 20 mins before the parade started, one of them went off and shortly came back with a few seats....think they took them off the sidewalk area. Well, a CM had been walking the route, talking to people. He saw this and quickly explained that no seats were allowed there. They argued with him, saying that they had been told it would be fine. He asked who had told them that, so he could let that CM know it was in error. They couldn't remember. Then they told this young man that one woman in their group had to have a seat...she wasn't able to stand. He was very apologetic, and offered to go get her a wheelchair. Oh no, that wasn't necessary, they said. He insisted...and went off in search of a wheelchair. Of course, when he got back, they had left! When I mentioned that CMs incredible handling of the situation, she told me that that CM was very good at his job! On our way out of the park, we stopped off at GS, a d said we wanted to report a CM. the poor CM behind the counter just got pale and pulled out a form. When I looked at it, I apologized profusely, saying it was a good report! He was thrilled.....said more people put in negative reports than good ones....a lot more. The form had space for everything I needed. I was told that the report would go to that area supervisor, who in turn would let the CM know. Then the report goes into the CMs personnel file. It is very helpful when they are being reviewed. So, if you have an outstanding CM experience, let someone know! The CM will be thrilled.
