It all adds up though doesn't it and I should imagine margins are tight and even if a few percent stop going it can make a difference.Remember over half the population agree with him over Brexit. 'Woke' customers may remember and care about Mr Martin's business practices but I doubt if they're his target ones anyway. I don't frequent student areas so may be wrong.
Even some of the Brexit-voting oldies who I attend the football with are principled enough to not use a business that screws its staff over.
I think the main customer base Spoons will retain is those that can't afford to drink elsewhere.
