We were at a market place on a new continent and were checking out the fruit stands.
Rogue: Are there any fruits I don’t recognize?
DM: You’ve never seen a kiwi before.
Rogue: Excellent. I buy a kiwi.
DM: But it’s full of citrus. Your character is allergic to citrus.
Rogue: I know that. But he’s never seen a kiwi before.
