Not-so-clever F/O asked one of my colleagues - his Captain for the day - which sectors he would like to fly.
Captains response - " Well thank you, I'll fly them all"
Made my day, that did...
In forty years of professional flying, only once did I have a First Officer that was 'not especially nice' and argumentative.
He was referred to the Fleet Manager...who promptly sent him home for three months, with no pay.
Many complants from other Captains, apparently.
