To say no

[adviceonthepox]

Currently at A theme park for a couple of days. Lots of school trips as to be excepted. Queue times for major rides can be over an hour sometimes as much as 2 hours. Stood in queue for a child's ride estimated queue time 20 mins so not excessive. After about 15 mins in we are getting close to the front (about 20) people in front a woman is pushing through going excuse me excuse me we need to meet up with the rest of our school group. I refused to let her and the 2 kids through. If it was the case we had accidentally got between them fair enough but as far as I'm concerned after 15 mins she was just being a CF push in cheat. She spent the next 5 mins moaning how the group was going to be split up etc etc. It wasn't fair on the kids, I had as being unfair to her group. I got on the ride,they didn't.
So was IBU?

Nope! Cheeky cow.

No you weren't. She should queue like you had to.

Oh and to say there was at least 3 groups of parents and kids in front of me and my children. All of whom said no, after I had said no!

She was being a CF. Either they stay together and get on togeather or realise they will need to meet up at the exit.

No, she was being a CF! If they wanted to be together that much the rest of their group could have let you in front of them. Or, you know, they could have all queued together like everyone else. Well done OP.
