Ok, then leave but don't call the police. Others in the restaurant may find the back and forth entertaining.Nope. I'll tell you why. It takes away from the overall happiness of the place. Two people taking over a thread (and I've been guilty of it, too) arguing back and forth, and not just arguing, but flinging the insults... if they were sitting next to you at a restaurant, you'd either tell them to shut up, or you'd get up and leave. You wouldn't just sit there and listen to it.
