If it was some nice guy really looking for a 911, I'd be nice. But it never is. It's always some scumbag. I just tell them to fk off. I have a bit of a pugilistic personality so I have no problem doing this.
When I had Seahawk's 356 a few years ago, there was one guy who got told to fk himself more the once. I said, "what are you doing here? I thought I told you to go fk yourself."
