I'm not so sure of that. I mean, how often, in the real world, do you see people blatantly cut in front of others in lines (outside of teenagers)? I see it happen all the time flying Southwest. You line up in groups of 5, based on your number. So like, if you have A17, you'd line up in the A16-A20 area. I've had people in the same group as me cram themselves right between me and another person, with inches to spare, instead of standing behind me where they have 5+ feet of room. Just to get ahead by one. I don't think you'd see that kind of behavior in the real world.
