Yeah, that's happened to me more than once. Some kid (parents nowhere in sight) tried to climb up and stand on my injured foot to watch IllumiNations. Waiting for Rope Drop at the MK, a woman was holding her preschooler so the kid's feet were dangling at my head level. The kid was swinging her legs and kicking me, none too softly, right in the noggin. I politely pointed out to the mother what was happening, and that the crowd was so heavy I couldn't move my ECV even an inch, and she just shrugged and resumed talking to the woman on her other side. I had to crouch down until the crowd started moving.
