Humiliated and embarrassed

I am so humiliated and angry at the specific lady who assisted me. Today 06th May 2022 I went into a fast food cafe called RingaCafe in Lephalale Mall, the lady who was taking orders by the Name W. Mudau(as shown on the slip), before she even got to my order, without even greeting she saw me in my work uniform and started talking of how she bought a product that I am promoting and didn't get any gifts and started of accusing me of being the reason, Infront of other customers in that cafe, Some of her other words I will not put down on this review but they were hurtful and humiliating. First of all I've never met her before and today was my second time buying in that cafe. Regardless of my uniform when I stepped in there, regardless of she was not satisfied of services given when she bought a product I'm promoting, she has no right to humiliate me like that and embarrass me like that, I'm a client when I walk in that Cafe and I have to be treated with respect, I believe respect is earned, and the first day I went in that store I gave the respect hence the service from the person who assisted me the first time I walked in there was of kindness, but she did not even greet and she was busy with another customer and started off talking such at me. I am not happy and I would really appreciate it if Hello Peter help me get my grievance across because I tried even telling her what she did was wrong and I was ignored.
