A few years ago a scruffy bloke turned up in a local pub I used. He'd spend a few hours in there nursing half a pint. The landlady, being business orientated and rightly so said to me one night when I asked if he'd been in that she'd banned him. I asked if it was because he only bought half a pint in the hours he was in the pub, thinking if so that was a bit harsh, but no, she told me she'd banned him for cutting his toe nails as he sat in the pub
, leaving the clippings on the floor
and then complaining that the beer was off and demanding his money back, after he'd drunk most of his half pint!!
