A chummer of mine, playing for the first time in a pub where I work a lot, finished up his show (that went really well), put his guitar down, paused at the bar to get the barman to start him a pint o Guinness, made a quick pit-stop in the upstairs head, and came back down to see his guitar patch chord spetched out across the floor, pointing towards the door, with no guitar attached to it... Some right bollox had the nerve to simply pick it up and carry it out on their way out the door...

A fecker like that (And yers) aughta have nails driven into their kneecaps...
