Jeff: Hey Joan. Do you want to have lunch with me today?
Joan: I would love to, but I have already accepted an invitation to eat with Mr Singh from the marketing department.
Jeff: Isn't he Indian?
Joan: Yes, he is from India. What does that matter?
Jeff: Well, he will want to have hot curries for lunch.
Joan: I cannot believe how ignorant you are some days. Do you eat hamburgers everyday just because you are an American?
Jeff: Of course not. That would be stupid.
Joan: That's right! Maybe Mr Singh would enjoy Japanese food for lunch?
Joan: Only if you promise to be culturally sensitive!
