Dollar General review: Manager

I went in store to buy a few food items as I usually do and all of a sudden the manager starts yelling from checkout that we're not allowed in the store. She said she reviewed cameras and we looked sketchy. She saId we needed to leave bedore she called cops. She never could tell me that I had stolen something or what exactly what I did that was sketchy. I feel that she didnt have to yell across the store in front of all of the other customers. Im embarrassed because she made me look like a thief and I feel like she was extremely rude. I guess buying things and looking at clothes is sketchy. I feel discriminated against because im poor and stressed and I look that way. Now I cant even go im a nd buy food as I have no transportation and everything too far to walk. Shes rude and should not be a manager
