"Ooh, and I think those who are really 'Professional' would want to be the last to leave the plane, after making sure no-one was left stuck in their seat."
No! They don't WANT to be. What they WANT is to get as far away from the aeroplane as possible. What they WANT is to save themselves. What they WANT is to go home that night and hug their kids. What they DO is stand there, yelling commands, coordinating the evacuation and getting bloody frustrated at people who waste time (their own and ultimately the crews') by dragging their bags and clobber to the exit, only to stand there in dull surprise, wondering how they're going to get themselves plus luggage down the slide!
