> Imagine walking in to a Starbucks café, order a cup of coffee, digitally signing a payment transaction on your mobile or laptop and then wait for it to be confirmed by the Blockchain while enjoying the hot cup of coffee you have ordered.

I think you can already pay contactless either by your mobile or credit card and without the need of Blockchain.

> What is more, think about AI, you will not need to talk to the staff to place an order for your coffee. The staff can relax and watch you make gestures to a camera. They will be able to read on a screen if you’d like it white or black.

In McDonalds you have automatic machines that you can place an order and pay, e.g., contactless, without bothering the staff. Later you only just need to pick your order up.
