If it didn't exceed the limit of coin usage (which i don't THINK it did) those 2 are on the verge of being fired. The customer is allowed to be rude but you are employees and you need to do your fucking job and accept the payment. I get that the guy was a complete dickwad and needs to be punched but you could have just accepted the money, it's not like you were talking a bunch of customers. Funny but both side are dickwads.

Wait nvm the guy played himself, he would have lost in court. I was looking up the laws and turns out they don't have to accept it past a certain limit and sometimes they can even reject coins all together. Well played dickwads go fuck yourself.
