There were a number of pubs called "x and firkin". I recall "font and firkin" in brighton. I think the original was in Lewisham. I reemember from around 1984. At some point they got taken over by M&B and went through a number of name changes.
It was a bit out of area for forum drinks..... My recollection is most people wore name badges with either their forum name or real name. Some people didnt want to reveal their forum id. I have some floppy disk labels I can donate to the cause!
