That was beautiful, man!
Something similar happened to me a few years ago. My bank decided to send DiscoverCard $750 instead of the $75 I had written on the check. Much hilarity ensued.
Because when Nurse Goodbody gets around to it, she is likely to just reverse the 992 and then charge the 9.92. The bank isn’t going to ding this poor guy more than they need to, let alone have to deal with even more hassles matching up another transaction.
