Oh trust me, these explosive episodes of anger are always on the incline when it's work because it is some sort of conductive/professionalism-induced stress where it all adds up in a small time due to physical and mental exertion.

I had two experiences similar, one was at an electronic retailer and got accused of turning a blind eye to a shoplifter whom took all the contents from inside a phone box, which never happened. Once we reviewed the cameras, I told her to **** .... herself and basically smashed a whole column of electronic-peer devices.

The recent one was finishing up our late-night Thursday shift around 7 @ the pharmacy, all accumulated stress from withdrawals and other external issues, felt an abundance of energy and went APE and started throwing all the assorted meds from the shelves around the store. Didn't end well, embarrassingly enough I stayed back to clean it up. \

Enough about that, I understand completely how it feels for anger to reach the pinnacle of action then out comes the true energy within you. I can't tell you which is the right and wrong way of expressing anger but deep breaths, screaming into a pillow, handling these situations less intensely could've prevented what you got now, a regretful conundrum. It's okay, what's done is done, it'd be wise of you to apologize but give it 1 week out the subconscious it goes.....
