Loser loses bet.
It’s a short story so I’ll only quote a couple of lines.
The man began to walk away, when , police say, he turned around and said “I bet you don’t have one of these”, pointing a gun in his direction.
The guest did have “one of these,” and began firing at the suspect. He reportedly hit the man at least once.
The “victim” apparently decided he didn’t want to play along and shot the would be robber. Didn’t kill him, though.
No charges are expected against the shooters. Although maybe a bit more target practice would be in order.
This goes in under the Sumdoap Chronicles category although “Victim Selection Fail” would fit the bill.
