The lady with the iPad situation sort of happened to me at McDonalds yesterday. I ordered from their touch screen. Their system told me to come up to collect my food but when I got there the person working asked me if I was different order number, i said no and she told me to stand away, I told her the system has told me to come up and I had not even finished speaking before her colleague handed me my order.
