This article brilliantly describes my thoughts on pubs offering discounts on flavoured alcoholic drinks (sometimes beer flavoured).   Blackpool was the first place to discourage drinks promotions as it not only attracted the wrong clientele but made the punter horribly drunk & then let the police / ambulance service cope with the problem.

How can a pub sell drinks at 80p each & still make money without serving drunks - & therefor breaking the law?

Again, a great article.
