I live in the states over 26 years. From east coast to west coast. I have never seen such horrible manner in a professional setting. The casino has dedicated high limit gaming area for Asian people which has dinning area. The restaurant employees treat you based on your tier level. If you are diamond 💎 their smiles are the cheesiest but if you are below diamond and not regular, they let you feel it to the point you don't want to go back there. Only race other than Chinese, that is treated well is white. They are so rude to everyone else. Fake smile for Diamond and no smiles for the rest.
