I've read the guv'nor as well, quite an entertaining read and McLean seems a decent enough bloke but he is what he is, a product of his enviroment I guess.
I fail to see why you wouldn't give your honest opinion to Courtney?
What's he gonna do? Pull out one of the 500 knuckledusters he owns and hit you with it?
Think his barke is worse that his bite...bit of a character I'm sure but not one I would take seriously.
