From what I know, he has an issue with keeping his cool. Which in the staff handbook states to always keep your cool. I do understand that he was angry. But thats not an valid reason to player diss. Not from staff. Not from a player. Also like Bennett said I have seen him abuse his phys gun off duty, and just have never had the time or be able to record it. I guess in a way the staff member could of just moved the guy away. However angry or not, dissing a player in any way is not tolerated.
So in all I think a talking too, and or a strike would be appropriate measure.
