To be fair though I think that a lot of publicans would be of the opinion that 'if they're brewing their own beer then they're cheap and they'll only drink at home anyway, so they'll not be a regular paying customer'.
It's pretty obvious that B&C recognise most of us to be a different kind of punter than the norm - most joe soaps would balk at a beer menu to start with, never mind paying a bit more for beer than is 'normal' in other pubs.
Try it in pretty much any other pub and i guarantee that the answer WILL involve rude words, and probably a gorilla in a tux helping you to the door.
