This is one of those ideas that is so clever it seems obvious, and yet I've never seen it done before. If you've ever set foot in a coffee shop (or are even sitting in one right now), then you'll be able to conjure the setting without breaking a sweat. Structuring the prompts as the spots on the back of a loyalty card creates opportunity for meaningful interaction between you and your fictional customer. The whole thing ties together so well that you'll start writing a story in your head as soon as you look at it.

It's worth paying to get all 10 cards -- you'll rarely come across something that stimulates the imagination so effortlessly.
