Squawk 7700, you are not an flying school provider, you don't know what you are talking about. Clearances into & out of Essendon without going into Class C above Essendon's zone do not incorporate level or heading changes. Quite often you are processed out via Kalkallo or Westgate bridge because your planned track cannot be accommodated.
There is a culture of 'fark GA, they don't pay' within ASA. It's justified by the table of priorities in AIP.
