Did i show him what he deserves?

Talk to your boss about this NOW...if this guy comes back in, your boss needs to know what's going on. for some reason, this guy feels like he has every right to put his hands on you...and he's wrong. Your boss should not allow this guy back into his establishment. What he is doing is simple battery, and ual ault. If your boss does nothing, tell the guy YOU will call the cops next time, AND tell your boss that, too. You don't need to put up with this crap.
