Call it Spring Stock Associate interview questions

I was emailed by someone in the company to meet the store manager in person. When I asked one of the employees if I could talk to the manager, she told me she'd be a minute and looked me up and down before walking away, which was completely unprofessional and rude. The manager took me just outside of the store for the interview and asked me a couple general questions. The interview went okay, but the manager's face changed after shaking my hand and turning to go back to the store. I just found the entire thing unprofessional.
