When we were there last month, we saw quite a bit of line jumping. It wasn't from any one nationality, it was pretty much everyone....but the vast majority were teenagers.
I don't have anything against teenagers (I was one, once upon a time) but I never would have behaved like these did. In line for Small World, one (large) girl stepped on my foot in her haste to shove my 2 year old aside and I kicked her
She looked at me and we didn't speak the same language, but my entire 5 feet of self were not pleased and she quickly jumped several more people. Other times they simply pushed past us and kept going right to the front...try explaining to your 5 and 2 year olds why we have to wait for the carousel when those people don't. We saw line jumping for almost everything and for the characters, it was horrible. Strangely, though, everyone stayed in their queues for food.....
In defense of the CMs, the line jumping occurred way back in the sort of "cattle call" areas of the rides, before you get to the "snake" barriers, so the CMs wouldn't be able to see it.
One also terrible example....Perla the Mouse was doing a meet and greet in front of the castle. This awful child (girl, about 10 years old) put a rolled up wrapper or some other trash IN PERLA'S MOUTH. Now mind you, the person in there can't see that but knows something is there. She tried to take it out but her costume fingers were too large. Then the child, laughing and posing for the camera, puts her hand up to Perla's mouth again....Perla slapped it away fast, and turned the child away from her and gave her a little push. The CM minder didn't see all this, because she was trying to hold back the crowd. Again, what really bothered me here, was that this child was laughing and posing for pictures while doing it. A small child could make this mistake, but not one that old.
