You are going to your local supermarket. That nice one you really like. It's filled with everything you need and want. You are walking through the aisles and buying everything your heart desires. Then, when you are done, you push your cart to the register and take out your Bitcoin card. The cashier smiles nicely. You pay 0.000000112 BTC and take everything you need for the week or more. Then you exit the store with a smile on your face and go home. This is the future.

I'm in heaven then :)
