IIRC Bank of America lost a class-action lawsuit over this practice. I didn't opt-in to overdraft protection precisely because of stuff like this. I'd rather just be denied.
I got hit with several overdrafts after some tickets I purchased finally got charged a month after I purchased them. Even better was that I never got any text messages to warn me. I set up alerts for low balances and whatnot, and somehow this was the one day it failed to work. If it had, I would have transferred money from another account and avoided any problems. I've been meaning to find a new bank (or credit union) since.
