lol - I am on the west coast and have met some New Yorkers! Their language and attitude stands out like sore thumbs!
I had one musician friend who visited New York City, went into a music store and the guy at the counter didn't even know where Seattle was located!
I knew a former cab driver from NYC that was telling me about picking up a guy who had just been stabbed. To my astonishment, he was still angry that he dropped the guy off at the hospital and didn't receive the fare!
