I dunno about the legality of this or not, but banks absolutely will refuse to give you over a certain amount in cash at any given time unless you notify them ahead of time of your withdrawal. They don't actually keep that much cash on hand. If you go to your local bank and try to take out $20k chances are they'll tell you here's $10k, come back in two days for the rest and call us ahead of time next time.
