The thing about that 'apology' was its belligerence. You can read between the lines easily enough: "Ok, you bitterz have got the hump about the Liverpool stuff we do and you got a cob on about it round the derby. You've made your point so get back in here".
A non-apology apology in effect.
You'd have to be a right 'kin scab to go in there and pay to drink their gnat's piss again.
I do wonder how much it's cost them. At the end of the day, it must have cost them money as otherwise they would not have apologised.
