I was intervied by the cash registers and hired on the spot.

When I got the call, I made sure to write down the interview time at 10 AM. I came in on time and she was already in an interview which I waited until she was done. I had to wait another 15 minutes while she made a phone call. She came up to me and told me that I was scheduled for an interview at 9 AM and basically told me was outta luck. Her attitude was very negative and condescending. I tried to tell her that I was sure it was 10 because that is what I wrote down as I was talking to her on the phone and she just shrugged and walked away.
