Left my purse in the dressing room and minutes later when I realized what I had done I was relieved to see my purse was still there! But....140$ in cash was gone. Store didn't seem to care. While eating M&Ms the security officer said our cameras do not face fitting room at all. Refused to do anything. Trying to question him about options was difficult as he was enjoying his candy. Very unprofessional.
