The incentives don't quite work like that though. With normal FIFO queues you're free to abandon your place in line if, for example, you decide it's taking too long and you'd rather do something else. If later the line dies down you're free to go get back in line and you're not being a jerk. However if you get stuck too far back in the LIFO queue, then it's actually in your best interest to abandon it and come back later. But there's no socially appropriate way to do this. I think if you tried to do this in the real world it would quickly devolve into a mob. Random order would probably work better.
