I am frankly shocked that there are companies that place such pressures on Captains.
If you, as Captain, decide to carry extra that should be an end to it. To 'shame' or require explanations seems to place a pressure to 'press on' when you could really do with the juice. Happy to say my own comany places not such pressure but allows you to secretly check your extra carriage against the average so you can still see if you are wildly profligate compared to others.
