Thankfully Beagle's arrogance and capacity for puerile dogmatic replies of no substance are not the views of the majority of GA pilots.
As an Atco, (or Twatco as Beagle has referred to our profession in the past), all we want is pilots to call and let us know where they are and where they are going and the vast majority do.
We are in the same position as the airport described by A&C and frequently have to vector Instrument traffic away from aircraft transiting but not squawking or talking to us, everyone gets a taste of it, from Cessnas training to Boeings and Airbuses earning revenue to keep commercial aviatitors in jobs and airports busy.
Today aircraft to be delayed was an ambulance flight with a critically ill child on board which had to be repositioned back onto the approach because some clot decided to fly through the final approach at 1500ft, at 6nm, sqawking but couldn't be bothered to call us. It took approximately 20 extra track miles and a five minute delay to the ambulance flight.
Its not simply a case of CAT being afforded priority when it comes down to landings and departures sequences, but common sense and safety.
Although I sympathise enormously with the cost of GA etc, the price of fuel is a problem GA have failed to do anything about for many years and is of little relavance in this scenario.
One final point, CAS isn't the Berlin Wall, the vast majority of airports with it (outside the London area) will afford transit through it usually because in their interests to know where you are and what you're doing.
