I need to ask if it okay first to throw scalding coffee on a customer who threw a lager can at me?
Do you really think it'd be okay to throw hot coffee at someone?
Its no joke. I want to do it to prove my point, that I'm not there to be abused by customers.
You should never hurt someone, even if they hurt you first. It's okay to defend yourself, but in this situation it sounds like you should just call the cops.
Well it's not like he didn't deserve it.
It's not okay to try to scald anyone, in any situation. I really think you should just call the police and file a complaint against this person.
