Doing a bit of research for the Lost Pubs Project website brought up an old local pub in Dartford called the Masons Arms - shut for some years now. In the day when I could see straight and my hands didn't shake so much I was part of 2 sucessful darts teams in the Windmill, Dartford. One night we were playing an away game at the Masons and a huge fight broke out amongst the customers with tables and chairs flying everywhere. It was probably the biggest non football ruck I have ever witnessed in a pub, something like the old wild west saloon brawls that virtually ended up in the street outside. I should hasten to add that it was nothing to do with us and we didn't get involved, in fact to my knowledge I have never thrown or taken a punch in a pub in my life, yet.
I also remember sitting in the Windmill once and a guy came in and for some private reason started to punch the living daylights out of another guy who just sat there taking it. When the punches stopped he looked up and said "if that's the best you can do you'd better f*ck off now" and carried on with his pint. The aggressor looked stunned and promptly left. A treasured pub moment.
Any other punch up memories out there...
