There are two sides to the story. I think the issue came with him starting to record things. Not sure why you would do that, but I can see where an FA may feel intimidated by that. Not saying this guy is 100% in the wrong, mind you, but I don't think we're getting all the details here, either.

Also, if I were paying the thousands of dollars for a F or C ticket, I wouldn't want the whole plane wandering in, personally.
