Friend of mine told me a story of withdrawing like $250k of cash. As a company the only problem was to make sure that you have an appointment in a bank (yes you can do that in our country).

So he withdrew the IOUs and later figured that the he no longer needs it.

So the next day he went to the very same building, with the very same bag of money to deposit it.

It took 2 weeks. With questions like WHERE DID YOU GET THE MONEY you terrorist! And answers like: in this fucking building!
