Good on Gary. Mind you, his actions are no different to what he and others have done before and no doubt will have to do again.
He is even known to leave the cockpit (flightdeck) to thank each passenger at the door as they get off.
A relatively common occurrence on the 767. I can think of a dozen names off the top of my head whom I know do it every sector. It wouldn't surprise me if there were many more.
Talking to pax in the departure lounge and the lounge during an extended ground delay is also a relatively common thing too. That said, Gary tends to do it with a lot more panache than most.
