This. I seriously doubt the OP said anything to the bloke. The kind of man that goes up and calls a stranger a ****, is not generally the type that then does the threatening thing on NSC 24 hours later.
Haha! Why would anyone get so upset over someone else's shit joke? I imagine the OP to be very much like the little chap in specs on that infamous video "You wan' some? I'll give it ya".
Seriously though, pathetic.
