There was a show depicting this scenario but I think it is spending 1million day. Cannot remember the title though. The guy is not supposed to buy things that he can keep, must spend on consumables and cannot be obscenely overcharged. After a while, it is damn tough. How much can one eat and drink?
nice show. I still remember one scene where he bought a priceless stamp and everyone was laughing at him (cos cannot keep mah). Then he used the stamp to mail a letter to himself.
