These notices offering “free” booze were all the rage at one time. Clubs and bars in particular were fond of this gimmick and it proved very popular with students. Critics weren't so keen and accused venues of encouraging binge-drinking.
Due to their dubious legal nature and a prohibitionist wind blowing in, they’ve become increasingly rare in the pub trade. So well done to our very own Wyldes for taking us back to the 90s.
