One very big point has been missed here, yup we can blame smoking bans and the price of beer, but the real issue is the breweries and the way they treat their Lanlords. From past experience i can assure you that Lanlords are being ripped off . Anyone with a Leasehold are in a no win situation. You take the lease on a pub with no trade, put your heart and sole into it, turn it round , make a viable business out of it, start making a descent wage from it and then the brewery comes along and says ' Hey Mr Lanlord, you're doing very well, we're going to put up your rent to a ridiculous amout, what do you mean thats not fair, tough, pay up or ship out '
I know this has happened to many many Landlords, myself included.
Also you are tied to them for buying your beer. You have to buy it from them so you pay their prices and thats final.
