What is the most "un-Disney-like" thing you have experienced/witnessed while at Disney? It could be something you overheard, saw, or *gasp* have done yourself...
I've seen quite a few, but the one that sticks with me the most is during one of our trips while at the MK, we were waiting in line for Space Mountain. In front of us was a father and his son, probably around 6. He was a little tyke, and when we got to the CM with the measuring stick, it turns out the boy was too short to ride. Instead of telling his son it was okay, and they would find something else to ride, he started to yell at his son, telling him it was his child's fault for not being tall enough, and how mad he was at him because now HE wouldn't be able to ride.
The look on the boy's face made me want to cry
