1 Introduction

Sitting in a Starbucks recently, I logged on to the free Wi-Fi to check my email and catch up on the news. I also had to make a call overseas and used FaceTime. As my call was ringing, I noticed people coming in and going to a side counter to pick up their coffee, which they had ordered and paid for using the Starbucks app. I then had a quick flashback to life before the Internet and thought how different this would have been before.
