Wow... that's pretty bad... Welcome to America. I hope that kind of rudeness doesn't bother you. You may be in store for alot of it, depending on where you're staying.

I've never had to deal with someone like that,and I've never had one of my kilts mis-identified. I once had someone ask me if my kilt was Black Watch or Campbell... I chuckled and said, "yes, it is." We had a good laugh about that one.
