A stranger to Glasgow met his pal at the station. It was obvious that someone had recently punched his face hard.

His pal asked, 'What on earth happened to you then?'

The chap replied, 'I've no idea why, but a barmaid just belted me in the face!
I was just killing a bit of time in a pub and my luggage bag was in the way . So,I asked the barman if he would mind keeping it behind the bar for me.
He was happy to do this. When I went back to collect it later, this barmaid was
on duty.

All I said to her was, 'Any chance of getting my holdall?' and she hit me!'
