I love arrogant “way to treat an A-List passenger” comment - like it’s some kind of hero badge.
The guy was probably being a class-A jerk while demanding privileges he wasn’t entitled to. It would be interesting to see a video of the original encounter.
Then to threaten a “tweet”. What a dweeb. His kids, particularly the 9-year-old, were probably embarrassed by his actions. Some example he set for them.
Waiters probably spit in his soup on a regular basis, I’m betting.
And until we really know how big an ass he really was, we can’t really know whether the gate attendant over-reacted. By then she might have even been questioning whether it was safe to leave him on the plane given his mood and behavior.
This started with him demanding special treatment and not graciously taking no for an answer. It’s all on him. Every bit of it.
