Family Dollar complaint: Refused services, racial

The night manager denies me cash back, because of her feelings for me as a customer.
I live behind your store, so I go nearly daily, at leat 3-4 times per week. I really depend on your cash back services, but to be turn down services because an employee doesn’t like me is concerning. I am not sure why , but it seems she tells me no cash back when the register just got customers to give the register money , Also this night manager closes the cigarette case early and tells us it is policy cannot sale ciggs after 9pm. The morning manager told me this was not so. Clearly this night manager makes up rules as she see fit.
As soon as I walk in the door she make huge announcement there’s no cash back It’s so annoying. I depend on family dollar , but refuse to shop there while she works there because she refuses me services. I must shop at roses, and corner stores and pay higher prices,
