Sorry, meant to skewer ExPat, not you.

I am quite tall and broad shouldered, and it is not unusual for my elbow to be jostled in the aisle when I am relegated to economy (hopefully as infrequently as possible). I always assume it is unintentional.

One pissy little FA did seem to be delighting in jostling me on one short flight. I just touched her on the elbow as I deplaned and told her it had been good to run into her on the flight. Don't know if she blushed, I did not wait around to find out.
