Ok good for you, I find it pathetic to continually let people be rude, break rules, and walk all over other people who are trying the follow the rules and do the right thing. But you go ahead and just keep taking it and taking it. Sorry I can't stand around murmuring into my armpit how I don't like that linecutter. I feel like the least I can do is let that line cutter know of my discontentment. It isn't ever about the the few minutes more I might have to wait, it's a matter of principle.
So based on the OPs story you wouldn't have said anything to the linecutter or to support the OP if you were in line behind her??
