I have been on several planes where people clapped at the end. You and I have quite a bit in common. I just roll my eyes.
One time I got on a bus with the same people from the plane and we took it to the terminal. When we stopped, I clapped for the bus driver. He didn't kill us either!
My wife was not amused... but I sure was!
I would have cackled madly at that and joined in with the clapping for example bus driver!
I am an eye rolling master at such stuff these days lol!!
