You could, for instance, let Google navigate you to any store when in a shopping center.

Google Maps is rolling out a new update that will allow users to navigate their way inside buildings like malls, stations and certain offices. This means that users can easily find their way to whichever store they are looking for when in a mall, or they can easily find the correct terminal while at an airport. The app will also use AR so that you can use your camera to see actual on screen arrows point you in the right direction. South Africa should get this update soon, likely within a month or two.
