On Blackpool's Pleasure Beach in the late 70s there was a cellar bar called Old Lil's Saloon Bar. Now, given the location I didn't expect much and I was not to be disappointed. The beer was dire and it was full of Manure fans celebrating a victory in high spirits, nothing worse.
What qualifies the place as extra shite was the bouncers who stupidly confiscated a balloon from the fans. It was 10.30 on a Saturday night, so the lads were up for reclaiming their balloon. This involved the throwing of various pub paraphenalia, including the wheel of fortune. Respect to whoever chucked that! I quickly retreated under a table and, once the fracas had subsided out into the Blackpool night.
The Yew Tree in Yardley in Brum was the most evil "normal" pub I visited - once, and that ended with fisticuffs and many thrown glasses. Normally I don't like modern shopping developments, but the one that replaced the Yew Tree has my blessing.
