If there is one thing that gets up people's noses it is an attempted clawback following administrators' cockups.
I know of a case in point where a Wg Cdr working for me [and working his balls off, being not double-hatted but treble-hatted] was in potentially very serious trouble for not checking his money every month. He spent half his year in and out of Bosnia, and was often working all the hours God sent. At the end of a year he had lost a lot of weight and was looking ill.
And he was supposed to check on the bean-counters work, unravelling the most complex calculations..
He was so busy he couldn't even spend his ill-gotten!
The service very nearly lost one of its best men, and this despite his line managers' cries of "you cannot be serious".
It was ever thus, people who just get on with it and trust others to do their jobs properly get mighty kicks up the arse.
