My dad went to the bank today to deposit a cashier's check. If there weren't a problem, I wouldn't be posting right now.
My dad was dead.
They had him as deceased in their system, circa 1967, but had neglected to cut his head off. I don't even know if that bank existed in 1967. Additionally, they had lost his signature card from about 3 years ago when he created the account.
He showed them several documents, and eventually convinced them that he was alive.
He signed a new signature card, and was reborn.
