Authorities said a would-be South Carolina bank robber left with a polite "thank you" after a teller told him she didn't have any money in her cash drawer. North Charleston police told multiple media outlets that 31-year-old Melvin Jesse Blain walked into a Wachovia branch Tuesday afternoon with a note saying he was robbing the bank and asking for $30,000. Investigators said the teller told Blain she had no money and he walked out empty-handed, saying "thank you."

Not long after, officers stopped Blain walking near the bank. Police said he told them he just finished a nearly four-year prison sentence for bank robbery and didn't want to go back.

Blain was charged with entering a bank with the intent to steal. It wasn't immediately clear if he had an attorney.
