"is an expectation coming from nowhere!"
Er, no, it's an expectation coming from ATC. Do you ever listen to other people? You must be a right bloody argumentative sod to fly with at times, especially drifting down at 100' per minute for your 1000' clearance. I'm sure the controller will love giving you those precious 10 minutes and 80+ miles.
