As I fly from one airport to another I speak to numerous air traffic controllers. Let's say I depart Grande Prairie (I think they're almost finished the runway upgrade) for Calgary. I would call Grand Prairie Radio, who would ask me to monitor the clearance delivery frequency. Once I had the clearance I would go back to radio, until after take off, when I would switch to Edmonton Centre. They clear me to my cruise altitude and on course heading, and then might switch me to Edmonton Centre on a different frequency to continue monitoring my flight. As I approach Calgary they will switch me to Calgary Arrivals (which is probably the same frequency as Calgary Departures), who will give me an approach clearance. If there are numerous approaches available at an airport, they may ask me which I prefer. If not, they'll just assign me the usable one. If the weather conditions are fine and I can see the airport, the approach may be "visual" -- no fancy electronics required, just fly to the runway. They can assign me the visual, or I can ask for it, but if I don't feel comfortable with the visual, or just want to practise my skills, I can ask for an instrument approach.
On this occasion I've just switched to the arrivals frequency and I hear the controller telling a pilot, "Everyone is doing visuals, but if that's what you really want to do, you can plan it." That pilot had obviously just asked for an instrument approach.
The pilot responds, "Okay, we'll do the visual."
We did the visual, too, as fast as we could and still get the gear down, because that's what tower (the frequency approach handed me off to) asked for.
