There's an effect I see in situations like this where the people in a big hurried rush end up being slow asses because apparently they don't care about this working efficiently, they just care about when they can stop waiting.
On a plane these are the people who leap out of their seat and block your row, only to start searching for their bag once it's their turn to get off the plane.
I see the same from drivers at red lights. If there are multiple lanes waiting to go, and one car has to inch forward every 5 seconds even though they are already way past the line, then in my very limited anecdotal experience there's like a 90% chance when the light turns green they just sit there for a few seconds after I start going.
