Family Dollar complaint: The cashier falsely accusing me of stealing something which was a lie I was sitting outside talking to the manager and the cashier asked me to come back in

I went to family Dollar with my kids to purchase items and while I don’t know what’s personalities I was standing next to the cashier and she turned around and asked me did I need something I said I’m waiting on my daughter to pay for her stuff she said I’m sorry we are coding is messed up please bear with me so I walked outside and came to talk to the manager my daughter comes outside and says that lady said come back in here you stole something so when I came back in the lady said to what did you steal I said no I didn’t steal anything ma’am I am a security officer I don’t steal she said yeah you put in your car and then you came back in I said no ma’am Ii was standing outside talking to your manager she then told me I had attitude and get out. I woke back out and explain to her manager what she had said to me and how it was and embarrassment to me in front of my kids Amanda said I know you didn’t take anything because you were sending us up talking to me. A manager said she’s been acting some kind of way she would have a talk with her but she asked if I want to hurt to write her up I said no then I just left. I feel like that was discrimination and stereotyping no one should have to deal with that and a lot of people know before I work and that doesn’t look good
