A guy leaves his place at the bar

A guy leaves his place at the bar to go have a piss. He comes back about 10 Minutes later, sits down at the bar, muttering and swearing very softly.

The barkeeper approaches the customer and asks what the problem is.

“Oh some son of a bitch snuck up behind me while I was at the urinal and put a gun to my head”.

“Jesus Christ! What happened?”

“He told me to give him a blowjob or he’d blow my brains out!”

“Yeah, then what?”

“Well you didn’t hear a gun shot, did you?”
