I remember 50 years ago in a bikers' pub in Swansea.......one of the boys would go to the bog and some of us would always drink his pint.
He got fed up with it, so before he went to the bog he'd spit in his pint and show everybody what he'd done. He thought that he was being clever by stopping us drinking it......and sure enough we didn't.
But instead of drinking it, we all went and spat in it! Some of the boys would even be snorting the contents of their nose into it.
He'd come back all smug thinking he'd got away with it.......and then proceeded to carry on swigging his beer. We'd be pissing ourselves!
Now this is the environment that I spent 40 years living in.......so is it any surprise that some slightly ill mannered behaviour may manifest itself from time to time?
I'm the victim here!
