He is one of the security team...the leader will usually find a space in first class, or the back of business. When they announce at the beginning of the flight that there are penalties for disturbing the order of the cabin, they actually mean it! And when they say that there will be audio and video files, they also mean that. I found nd it strangely comforting. Of course it doesn’t stop passengers (mostly elderly Chinese) getting up and opening the overhead bins while the plane is still taxiing.
