Dollar General / Rude employees/unethical behavior

I went into the Dollar General in Palm Bay off of Jupiter on 1/11/18 at 9:55 P.M. The associate explained there was 4 minutes left to shop and there were other customers in the store as well. I was the last to check out and my ride had went down the street to purchase gas and was coming right back. After a few minutes an associate( the best way to describe her would be the only black woman working)asked if my ride was coming and I told her yes. After a few more minutes the associate asked if I would move away from the lighted area and away from the camera and move myself and my items to the end of the parking lot to a dark area next to the street because I was in the camera. As I explained to her that people are warned to stay in the lighted areas at night for safety reasons, she then proceeded to threaten me with law enforcement. This is not o.k.
