AMPM.com review: Harassment

I am a vet. I'm 65, there is this one employee female hispanic with black hair. To days date jan 31 at 3:35 pm I went inside amom to get my coffee like I do every day and she questioned my purchase. I had found a free coffee card in my car so I used it. She asked me who is stamping these for you? And she told me she has never seen me pay for a coffee. She has the wrong attitude to work with customers and this happens every time I go there she is the only one that has an issue with me. Please ask her to get off my back. Thank you
