Arrogant Actors

Every now and then, I come across a fellow actor who is so arrogant it makes my teeth bleed, or maybe the person in question is just insecure?A friend of mine was in a play with a bloke straight out of drama school.
It was a really funny and charming production of a renaissance comedy, performed in a typical little fringe theatre above a London pub.This bloke was good and seemed to enjoy his part.
After the performance, I hung around waiting for my friend, when this guy emerged, desperate for a drink, and headed to the bar.
I approached him and told him how much I had enjoyed the production, and his performance in particular, but he just seemed to brush me off, grabbed his water from the bar and dashed off again.I found his behaviour rather peculiar- here I was, ready to heap praise on him after a rather busy Friday night, and he didn't appear to want to know.
Thirst didn't explain it, as he disappeared after he had his drink.
I got a feeling he really didn't want to be there: he hated the chavvy pub and the simple theatre, and appeared to think he was something better than my friend and his fellow actors, and especially the punters in the pub. Sad, really.
What was even sadder was that my friend had developed a crush on him and he had brushed her off in the same manner as he had me when I tried to compliment his acting, always disappearing back to Kensington when the other actors stayed for a drink and socialised with the audience.
One night he agreed to drive her to the night's performance. She went to meet him at his house.
Turns out he lives at Kensington Palace...
