I also don't say anything and just let them pass in regular lines (I'm always in LL queue) because I don't know the situation (maybe they had a bathroom situation, etc). What gets me is when people start aggressively pushing past you at GoTg as you make your way from show to ride queue. breaking up my larger party, I will say excuse me, this is my party and I'm trying to stay with them. As others have said, its pointless to let it ruin my day, but if you start tromping on smaller children in my group to push past, I can't let that go as easily.
