A conversation overheard

Ben overheard this conversation between Daniel and Elizabeth. They were playing some game together on their devices which involved Elizabeth making a BBQ and inviting Daniel’s character.

Daniel: What will you cook?  Chicken? Pork?
Elizabeth: No.
Daniel: Beef:
Elizabeth: No.
Daniel: Mutton?
Elizabeth: No, none of those things.
Daniel (in a despairing tone): If it’s a vegetarian barbecue then I won’t come!
Elizabeth: It’s a vegetarian barbecue.
