Don't you just love our drunken Irish mates?

I was in the chippy earlier, a couple of Irish lads worse for drink came in behind me. All very matey and cajoling one another and myself that was until the girl asked "what would you like?" "aye giz a fish supper was the reply. The girl was non plussed "haddock plaice Cod pollock"? one of the irish fellas shouted "pollacks, in the name of fuc'k can't even get a chip wi-oout them polish ******* getting in, watch it love theyed steal yer job and your breath. I was creasing up trying to hold my laugh in. Funny as hell but embarring. Do the Irish not have a modi of decorum?
