A lady in line with us at one of the resort bus stops yelled at my family and I once (we were at the front of the line and had been for about fifteen minutes when she began to berate us). She was yelling at us to go to the back of the line because my brother-in-law had forgotten some important heart medication at the room we were staying at, and he left to go retrieve them. I'd understand if like, five of the six people in our party had left, but it was just him, so...
I don't like line cutters, either, but I also hate people who complain about every little thing such as the lady I mentioned above... especially while it's about waiting in line at a freaking resort. She had the audacity to call us liars, shout obscenities, threats, and shoot us the finger while we were boarding the bus, too. Needless to say the parents with young children in line with her were not very thrilled.
