Dollar General complaint: Manager out of line

This manager there yelled at me and trespassed me all because somebody I was talking to outside had went and looked in their dumpster. I was looking excuse me, because I was right inside in the from if the store looking at stuff and she barges in the store yelling saying your trespassed, and I was confused, and was like me?? She said because the lady I was talking to looked in dumpster, and I told her well I didn’t, I don’t have no control what other people do, that’s on them, but she totally didn’t even care, she told me to go that I was trespassed. I couldn’t believe that. And that was definitely not the first time she acted like that, so many people have told me she is the rudest person there is, and now I see why. I was so mad. I still am. She does not need to have a authority job what do ever. Unprofessional.i really hope this get looked into
