I'd be seriously pissed if I had to jump through that many hoops for $20,000, or even higher. You're a
bank holding my money, not my mother deciding if I deserve an allowance. My official reason for the withdrawal is "None of your business." Maybe I want to buy a used car for cash, maybe I'm helping out a relative, maybe I'm paying a ransom demand to make sure kidnappers
don't return my mother-in-law! It doesn't matter and, no, I don't have to explain what I'm going to do with MY money.
