I agree, just because you are a cm doesn't mean that you are suppossed to be some kind of perfet AA with no emotions that aren't pleasant. We are paid to make magic happen and provide personal service and experiances to the guests. Such personal involvement means that you are going to encounter stupid things and people trying to take advantage of you. Without a forum to vent and gain some perspective on the more frustrating aspects of the job, I can tell you there would be a lot more complaints at city hall about rude CM's. We are human too!
The kicker about it is that many of the stupid things guests do get them or others hurt and ruin the parks for others. Just because you bought a ticket doesn not give you the right to do or say or behave however you want and many people seem to forget that. A little curtosy would go a long way and it is not just the CM's who should remember that!
