i dont know him but i have seen him several times in the same pub where me and friends drink.
never had any reason to speak to him and to be truthful the guy is just out enjoying a quiet pint with his own friends
everyone in the pub leaves him alone for that reason
o0o so i kind of have a link to him !! considering you know him as a familiar face say i was your girlfriend and we went to the pub i would walk over and lay on the charm! but sadly i'm not and i don't live in london
