I hate line jumpers! If one or two people join their party, that is ok. If parents need to get their kids to the potty and the wait time for the ride is 2 hours that is fine. Letting 20 jump in line because you are a group, not cool. I am a busy body, so naturally when the 10th person stepped in front of me, I said something. They did not respond kindly to my words and since they out numbered my group, I shut my pie hole.
