I always have to laugh when, at the end of a flight, the majority of passengers jump up and elbow their way into the aisle, even though in many cases they'll be standing there for at least 5 minutes.
While sitting in the aisle seat, I've had passengers that were sitting beside me fall into my lap as they try to jostle their way by, just to get a place in the (stationary) line.
What's even funnier is when you see these people waiting around the baggage claim 10 minutes later.
Crowd psychology is a funny thing.
