I was in the supermarket, looking for, among other things, shallots. Since "shallot" means different thing in different countries, I'll specify that I wanted these things, what Americans call "shallots."
I went to the shallot bin, but it was blocked by a young couple. The woman was selecting shallots. Since I wasn't in a hurry I waited for them to finish.
Man: That's a lot of shallots. Do we need that many?
Woman: The recipe calls for 6 shallots.
Man: Wait a minute. Doesn't it say 6 scallions?
Woman: Scallions, shallots, they are the same thing. [they walk off]
It took a minute for it to hit me. If the recipe calls for 6 scallions (green onions, spring onions) and she is going to use 6 shallots, it just might be a very interesting outcome, especially if the scallions were to be minced & used as a garnish.
(In the US, "shallot" never means "green onions," and the young woman's accent was in no way Australian.)
