This sounds like that story of the elder withdrawing $20 at the bank: Elder: I want to withdraw $20 from my account. Teller: You can withdraw $500 minimum here, or use the ATM for small change. Elder: I'll withdraw $500 then. Teller: Here you go. Anything else? Elder: I want to deposit $480 in my account.
