Quick Exit
I suppose when you look at it, those at the front and at the back (if rear stairs are available) could benefit from a quick exit. I have found though if I happened to be about mid cabin, it does seem a bit of a waste of time getting up too early. I have not yet had the experience where some one is telling me to get up sooner than later and if I am in a hurry, I will usually try and get a seat further up front anyway. I think there is nothing wrong with the crew asking passengers to deplane quickly without sending the message that they are trying to get rid of you. It's a shamethey dont unload through aero bridges at the back as well.
