If I were you, I would report her stupid arse!
She had no right to say that, I would most definitely report her!
I don't know what it is about people behind makeup counters (especially Clinique, because I've had the same type of trouble), but they can be major biotches sometimes! Granted, I can understand if someone is having a bad day, but to call someone names? Nuh-uh, no one should be calling names like that!
Report her!
