Not sure what the joke is, Beagle.
The normal procedure is
1. Plan the OCAS route
2. Plan the more direct route
3. File an ICAO flight plan (if applicable) using the more direct route; abroad this does tend to get distributed "properly" to the proper controllers along the route
4. On the flight, ask (in a very firm tone) for every direct clearance you can ask for, giving the immediate route as IFR waypoints so they can see you are navigating using some proper means and not fishing for villages and ponds which CAS ATC units hate because it makes their life hard
What tends to frustrate the above a bit is the determination of some UK ATC units to send a VFR flight to VRPs when they can see perfectly well you are navigating via radio. This happens abroad too, but isn't a big deal because the official VRPs near airports tend to be in the GPS database. I am not sure of the legal position; I believe a VFR pilot is entitled to navigate by radio when en-route, and in fact some countries (Greece being one) WILL expect VFR navigation by VORs and airways intersections.
I won't take your "playing airliners" bait.
