How I dealt with a conflict at work

So I got hit at work today. So what I did is told security about it first. Then I told my supervisor.

It's not that it hurt or anything. Quite frankly I've taken far worse. It's the principle of the thing.

It was uncalled for. Thing is if he hits me, then who won't he hit. I'm 5'6", and a blackbelt. Now I didn't press charges because maybe he was just joking around. He's got a family. But if he does it again I will.
