I experienced this in a pub called the Kilcreggan, funnily enough in a place called Kilcreggan, just west of Helensburgh. I’d gone to watch a footy match - a Liverpool European championship match - not a supporter, but I’d left the Missus & Mother in Law in the cottage- you get the idea
Any way, I was propping up the bar having a quiet Tennants when I became aware that one of the two very pissed blokes sat at a table trying to talk to me & all I could hear was “Weegie, Weegie, f*ckin Emilie Heskey, Weegie, Weegie”
I ignored him, which seemed to wind him up so he staggered to his feet & drew him self to his full height of 5’6” although he was that size wide - he then stood by me giving it more Weegie F’Kin Emile Heskey, I told him I couldn’t understand a word he was saying & told him to f’ck off & leave me alone, the young barman intervened, but he just got a mouthful of Weegie obscenities- some of which I could understand, just before it really kicked off, one of a group of middle aged women stood up & and from what I could make out, threatened to tell his missus that he was pissing his wages up the wall, he went quiet, finished his drink & left.
According to the barman, the guy had got off the fishing boat after 4 nights at sea & armed with his cash wage packet had been in there for 8 hours.
While I would have had no problem in “defending” myself I’m not sure which way the rest of the pub would take it, so I count myself lucky.
