The SA associate was rude and acted against corporate policy. She was probably showing her bias. That being said, PLEASE do what my wife frequently does.

My wife will call or email or write a letter telling a store manager or the corporate office about GREAT service. Frequently when she calls there is a pause which is followed up with "Your calling to tell us the sales associate did a wonderful job. Nobody ever calls to offer a compliment!" Well, my wife does.
