if some cpt flys fast, gets a short cut, or taxi fast and robs me of double time that person is getting throat punched.
it's like the dude who wont pop the brakes to get on the clock when you know you'll have overly because they're waiting for ground crew to find a working headset.
pro tip- you can still release the parking brake, hold the brakes for 3 sec then put it back on without the plane magically rolling away. That way you can start the clock.
