Stater Bros Markets review: complaining about a cashier: kim. m

I am sending in my complaint about this lady cashier who made me feel very hurt emotionally. I bought some thing and asked for cash back.. She didn't give me my receipt that showed my cash back she had to give me back. I personally saw her trashing it and wondered why? So I stood on the side to let her work on other customers because she had called in for more cash to be brought in for her. When her manager brought in the cash... She asked me the receipt and I answered her that she didn't give it to me.. she kept on insisting that she gave it to me. she started asking me why she would do such a thing not to give me a receipt that will prove how much she needs to give me back. I answered her that I saw you trashing it. And rudely she kept asking me the same thing why she would trash it? I didn't know what to answer her any more coz she made me look stupid and a lier Infront of so many customers. Surprisingly when she checked her trash... She got my receipt... And she didn't even say a sorry for the lying that she gave me the receipt like she was saying at first... I don't know if she disrespected me just because am black but I think it was very wrong. The least thing one can do is to say sorry... she has a poor customer service...
