Some of the replies and the implied attitudes displayed on this thread make me feel quite glad I'm no longer in the game of running a MATZ and having to deal with those who think as some do.
The end aim is, has always been, and (in my own opinion)
should always be
SAFETY. If a controller asks/tells you to do something in airspace they are responsible for, please consider that there might be a good reason for it, and that the controller might be a bit busy and unable to give a full explanation on air.
A phone call to the ATC Supervisor at the unit once landed, however, could clear the air quite nicely and calm will be restored to the aviation community rather than banging on about it on an internet forum armed with part of the story. ATC doesn't bite. Just a thought...
