When I visit my parents, I often fly to the major airport a hundred miles or so from them and take a bus from the airport to their town. There used to be a desk in the bus station attached to the airport where you could buy tickets, ask the clerk when the next bus to your destination was, etc. A few years ago they got rid of the desk and have a sign with a QR code to download an app that gives schedules and let's you buy tickets. There is no other way to ride the buses now. This is just one example of how there's an assumption of "everyone has a smart phone" these days.
