In the early 80's in Australia, if you took money out of an ATM after hours or on the weekend the bank wouldn't know about it until the next business day.
So in my broke student days with $200 in my account on a Friday night I could go to five different ATMs and take out a total of $1000. Only did it once and got a nasty letter from the bank on Monday asking me to put the money back in but no overdrawn fees
