Dollar General Sales Associate/Cashier interview questions

Applied online. Received call to schedule an interview weeks later. Interviewer (Store Manager) complained that I showed up early (because she wanted to smoke a cigarette); I offered to wait and she refused. In twenty minutes, I may have been able to speak a dozen words, which were mostly loudly cut off by SM who rambled about current associates. I was told a background check would be submitted (the only disqualifying factor being a felony) and I would be contacted when the results were received. After a week, I called to check in and SM claimed she was still waiting on results. A few days later, I received a copy of the background check and a notice that I had been disqualified from consideration due to a misdemeanor several years prior.
