dkh51250, thanks for the memories, especially the Mucky Duck (The Swan) used to serve fantastic Chicken & Chips in a basket, the Vaults if I remember had a radical idea to stop people getting drunk by serving beer in half pint glasses (actually I am sure they used to be plastic as well), and then couldnt understand the increase in drunkeness as people swallowed two half pints quicker than one full pint so actually ended up drinking more in a shorter time. They also they could not grasp why two people would turn up and order 4 half pints at a go.
Don't forget the ones that changed names or changed clientele, the Cheltham Arms now has a fancy name that escapes me, but has at one time been Lincolns druggie hangout and the Green Dragon was a good pub to meet and pick up the local talent, but it ended up as a gay pub for a while.
