Turning up at work "almost 6 hours" before report? Dedication ..... or extreme anxiety?
Culture. You have to be seen to show before your superior.
There's a race of sorts in flying. Punching in transponder codes before the ACARS PDC has finished printing, calling 25% N2 at 23% so you're not late, etcetera.
I mistakenly sent a PDC request before the CA called for it. It was available, of course, but I hid the printout and requested a new PDC at the "correct" time.
