(I have moderate competency in Mandarin Chinese, but it is not apparent because I’m not Asian.)

Me: “Hello! Can I help you find anything today?”

Customer #1: “No, we’re just looking.”

Customer #2: “Just looking.”

Me: “All right, just let me know if you need any help.”

Customer #1: *in Mandarin* “I told her to go away. She doesn’t listen!”

Customer #2: *in Mandarin* “She’s a dumb girl. Just ignore her.”

Me: *in Mandarin* “Hey look, the dumb girl speaks Mandarin.”
