Japanese delicacies

Last night, at the Association for Linguistic Typology banquet, I was picking up some sushi rolls from the table when an elderly gentleman (his name is E---- K----, I later discovered) said to me, "Aren't those delicacies from your country?"

I was like, "What?"

E---- K---- clarified by asking, "those are Japanese, aren't they?"

I was so shocked that I didn't know what to say. I think I said something like, "Close, but not quite," and ran off.

Who says linguists can't be racist?
