KeyBank assessed me $360 of overdraft fees for a single day for a similar thing, where a check/cash was deposited (and it wasn't related to check deposit policy, that much was multiply verified in the arguments with various managers), and I went shopping with my partner for Christmas afterwards.

I'm no longer a KeyBank customer (in between that and them cancelling my card for a $1 Roku pre-auth charge as 'suspicious' - but not notifying me, calling, etc, just popping a letter in the mail which arrived three days after I discovered for myself it was cancelled), unsurprisingly, as they refused to budge on waiving the fees (except for one - "you get one courtesy fee waiver per calendar year". The mind boggles).
