It really makes me angry when people like that lady actually run into me when I'm in front of them. If I'm keeping up with the flow of the crowd, and there are hundreds of people in front of me (like after Wishes), then where am I supposed to go?
I know it doesn't sound like a really big deal, but I actually got my ankles bloodied by a wheelchair that ran into me on MSUSA. That time, the person pushing the wheelchair was at fault, and I knew that they were too close to me, but again, there was nowhere I could go. The person pushing the wheelchair did apologize, but they really shouldn't use those vehicles as "crowd battering rams."
Okay, I'm done ranting. Most of the people I meet at WDW are very friendly and are simply trying to enjoy their vacations. It is just that "rude minority" that really get under everyone's skin sometimes.
