(I’ve just finished ringing up a customer. Note that I have a very noticeable Australian accent, as I am from Australia.)

Me: “Have a nice day!”

Customer: “You too! By the way, I’m surprised, your English is really good!”

Me: “Er… thanks?”

Customer: “No, really! I mean it! If it weren’t for your accent, I’d have no idea you were French!”

Me: “Um… actually, I’m from Australia.”

Customer: “Oh, nonsense! I know a French accent when I hear one! Come on, say something in French!”

(To humor her, I make up some random sounds that vaguely sound like French, as I do not actually speak French.)

Customer: “See! I knew you were French! So what does that mean?”

Me: “It means, ‘I don’t speak any French because I’m not from France.’”

Customer: “Oh, you! You French have such great senses of humor!”
