You don't deserve a brake today

I heard about a woman in Georgia who decided to exact a little vengeance on two others who cut in line in front of her at a McDonald's. It seems that there was a long line and when another register was opened the two victims came from further back in the line enraging the person who had been in line longer. Now I'm not saying that physical violence is justifed by this sort of behavior, but there is probably a little part of us that had to think that it's a little, albeit extreme, poetic justice. The two victims were not seriously injured. Why is it that when there is an obvious crowded line that people who are nowhere near next in line think it's ok to just insinuate themselves to the front? Is their time more important than the rest of ours? Of course this sort of thing could be easily remedied with a system similar to the one many banks use, with a single queue that distributes the next person in line to the next available register. I'm sure all parties involved however will sue McDonald's for one thing or another.
