More weird things that happen at Chinese food buffets

Upon entering the Chinese food buffet while visiting family, my husband's uncle introduced me to the cashier (they visit this place often). She looked so confused when he said "This is my niece!", she was like "OK" and then she asked me "Are you his niece?" I shook my head yes, and then pointed to my husband. She then asked "Are you guys married?", like it was still illegal for blacks and whites to be married. We got that a couple of more times from a couple of more employees at the restaurant.
