Let's say this CM did either sell it to you or make a little 'magic' and give your kid some, against whatever rules they are supposed to abide by. Now, let's just say that a supervisor or who knows what was watching, and saw them give popcorn away, after the line was closed. What's to say that giving that popcorn couldnt cost the CM their job??? I'm not saying that would've happened, I'm saying that's probably a pretty slim chance of the person getting fired / in trouble for it, BUT the possibility exists for that exact thing to happen. How would you have felt if that person would've gotten in trouble for making 'magic'?
One of the PP's mentioned something about talking to a 'dream squad' person. It sounds to me like THOSE are the people that are allowed to 'make magic' for guests. They are the ones that are somewhat outside the rules, but maybe not ever CM is allowed to do that.
