You've tried the coffee?
Tangential to the free aircrew rations is the question of free food and accommodation when away from base. I don't know the present rules but at one point there was a plan to charge for food and accommodation for more than 24 hrs. This meant that the Nav School, flying to Germany or wherever on long airways flights on Friday afternoon and returning Monday would attract food and accommodation charges.
Now this might have been no great hardship for a one-off 'perceived' jolly with all the 'excitement' of a run ashore in foreign climes. For the staff pilots flying what was essentially a weekly bus trip into Europe it was quite different. They were giving up a weekend with their family on at least a monthly basis and then being expected to pay for the priviledge of working the weekend. I don't think they got proper time off in lieu.
They quiet calmly said if we pay then we don't night stop. This would have meant everyone having to open the airfield late on a Friday to recover the aircraft and also for the groundcrew to do all the pre-flights the following Monday - all extra work.
The charges were scrapped.
