Credit union tried to put my money in the wrong account. I caught the error right away and they fixed it, but now I know the name of someone with an account number that's the same as mine except two of the first three digits are transposed, so that's a bit of a privacy fail despite an apparent effort at not disclosing that sort of thing (the first half of the account number is redacted on the receipt, but it's a short enough number as to not leave many possibilities).
