I first saw Lenny Henry at a station in Kent where he had been appearing in the theatre, a group of young kids ran up to him and asked him for his autograph, he told them to F*** off, the next time was at a charity do and he was the speaker, he was all over everyone when he was performing, later in the bar the man who had hired him thanked him, he said "Look, I have finished working now, just piss off and leave me alone".
Bit much towards the guy that actually hired him.
That guy may have wanted to use him again for something else.
I know if someone said to me in the same situation, 'Let's use Lenny Henry again, as he was good last time', I would point out what happened in that situation.
Thankfully the job I'm in does not involve me in that sort of thing!
