Neptunus Rex, how often that sort of thing went on back then!
Having done a tour on the Tin Triangle and armed only with a copy of Strike Command accounting instructions - plus the plea "Do NOT put any booze on the bill!" - I once did some accounting stuff for our F-4 detachment which had been royally screwed by the host station. When we finally flew back to Wattisham, I gave them the forms to sign and said "Shut up and do what I say!"....
They all received a reasonable sum in unclaimed a££owances, having been completely unaware of their entitlement.
Yes, they took the pi$$ with some banter. But I was rather annoyed that not one of them ever said thanks....
