No he said "when you are BEING asked to leave a seat, you should handle it in a different way" so he obviously meant the passenger. You know, when you've paid hundreds or thousands of dollars to fly on a plane, and then at the last minute, somebody comes up to you and says "I am sorry but you can't fly today and you need to leave the plane right now" you are supposed to reply, with a smile and reply "Oh what a shame. I was looking for the flight experience with the cheapest United Airline that has seats barely wide enough to cover my butt and just enough leg room for me to put my knee in and when I need to go to the bathroom, a whole row of passengers have to get up to let me pass" but I understand. I don't at all waiting another several hours for another flight. And if that flight is overbooked, I will happily leave that flight too and I will keep on getting flights and possibly getting bumped off until I catch a flight that has just the space for me. My life and my career does not matter as long as United Airlines makes more money." and then promptly stands and gathers your belonging and walks off the plane in a cheerful brisk walk of happiness. Anything short of that is "immature".
