I was shop at Costco in Sunnyvale, California location on October 3,2016. So I decided to order a large pizza to take home. The server was very rude to me. She handed me my pizza without giving me plate and small packages of cheese and pepper. So I asked her very politely for a plate. She simply told me that my order is ready and she walked back to the kitchen. While I waiting at the counter to speak to another server for a plate. A lady next to me who is Caucasian also ordered the same thing that I did and the server gave her plate and small packages of cheese and pepper without asking her did she or not. At that moment I realize that I was being discriminated. So I asked another server for a plate. She handed me my plate with an attitude. I'm very sad how I had been treated by Costco employees. I'm thinking not to renew my membership next year.
