(I work at a marble slab creamery. It is a type of ice cream store that allows customers to mix in candies, cookies, etc with their ice cream while it’s kept cold on a frozen marble mixing slab.)

Customer: “Hi there. I was just wondering what the name of this store meant. I never understand these metaphor names.”

Me: “Well, ma’am, the name is about as literal as it gets. We mix the ice cream on a marble slab.”

Customer: “Oh, so it’s an allegory.”
