Rude waiter

I was at the restaurant with friends and there was basically a misunderstanding regarding our bill. So we call the waiter and I'm explaining what happened, card in hand ready to settle this bill, he basically tells me off and rudely tells me a paying customer to "leave him the hell alone" I call the manager, tell him what just happened and he takes eons to attend to the matter. I was truly not impressed. Didn't enjoy myself there at all
