How would you use drones and robots in a coworking space?

We’ve been looking (especially Jurjen) at a lot of very cool applications of technology in coworking offices and regular offices. Think of an app that opens your door and checks you into The serendipity machine, beacons that know exactly where that person is you are looking for (based on knowledge for example), or a smart thermostat that goes down when it becomes busy at a location.

Let’s give our brain a spin. This cool little drone costs next to nothing. What would you use it for in the (coworking) office?
