I once experienced the opposite: after I released the new captain, he became very company-minded.
There was a (minimum) flight plan fuel reward “system” in place....which he was “rewarded” for.....
Than, 1 day, surprise, too long at the holding point and got below min required.
He went back to stand, refueled and departed with more than 1 hour delay.
And flight time was around 2 hours, destination 2 separate runways with severe CAVOK conditions.
The guy was an ex military Eastern Europe bloke, changing to the civilian world.....😴😳
