Does Moist von Lipwig skim money from the Post Office in the Discworld novels? I don't recall any reference to him doing so, and given he's a Boxed Crook who was hung to within an inch of his life for fraud it would seem rather risky even by his standards.
(There is a reference in Making Money to the fact that four copies of a very rare misprinted stamp worth fifty dollars are in his office, in case of emergencies, but there's no reason to believe he didn't pay the full two dollars face value for them.)
EDIT: I've removed it, because the more I think about it, the more I'm not even sure when Moist could have skimmed from the Post Office; at the start of Going Postal there's nothing to skim, and by the end, he'd be skimming the money he poured into it, and which Vetinari is keeping a very close eye on. And I've just re-read Making Money, and there's nothing there about it, except arguably the stamp, which I'm not sure counts as mentioned above.

Does Bruce Wayne hiding his bat-technology purchases in Wayne Enterprises expenditures (e.g. Justice League Watchtower as a line item in the Wayne Aerospace budget) fit?
Does it still count if the person taking from the till doesn't work there as a cashier?
