I saw something like this at my local credit union. The lady in front of me was trying to withdraw like $1k. And she was giving this big, long explanation for why she needed to pay for part of her rent in cash.
I was shocked that it was any of their business why she was withdrawing the money. So I asked the teller and he said that they are trying to protect customers.
Screw that! If it's my money and I want to use it as fire starter, that's my business. Give me my money!
