Racially abusd

A white lady was gambling on a machine I liked in the smoking area at the casino. it was noisy as people are winning and drinking. I was standing behind the lady waiting for her to finish as liked the machine. she then said 'stop making noise you ****ing ******s'. we called a security guard but things turned on us when the security guard started pushing me around and said 'I am not allowed to stand near the lady as she is complaining now. I tried to explain that she is the one to be reprimanded because of her ****** comment. the head of security then man handled me and my wife, and we were thrown out of the casino. the security did not even want to listen to us, he said we should leave the white lady in peace.
