on the coming weekend. This is her usual time for playing since she is very busy during work days. She will be partnering with her husband and playing doubles against another couple, with whom they play often. They don’t have any speciﬁc time in mind but know that they would like to play on Sunday morning. While she’s on a launch break, she logs in to GotCourts site using her browser and is presented with a page where she can immediately book a court by choosing date, time and location. She chooses a club which is conveniently located for both couples - it has a restaurant so that they can have a cup of coﬀee after the game and, of course, has available courts for Sunday morning. She double-checks by phone call with the other couple about the exact time - 11 o’clock is suitable for them. After she gets a conﬁrmation from them, while still on the phone she books a court for 11:00 for two hours.After the booking has been made, she is given a conﬁrmation of her reservation. Emma informs her friends and sends an SMS to her husband.
