<prompt> Human: So I went to the bank and deposited some checks and cash. They deposited one check as 10x what it was worth. I called and told them. Currently they took everything back out and put back in the right value for checks, but none of the cash is in. I have two questions:Should I just wait and see if they fix it over the weekend?What would have happened if I didnt say anything? Could I have kept the extra money?Assistant: Should I just wait and see if they fix it over the weekend?That would be my recommendation. Im assuming you live in the US, so remember that July 4th is on Monday, so nothing may be corrected until Tuesday. What would have happened if I didnt say anything? Could I have kept the extra money?Not in your life. Banks have an adjustment department that double-checks deposits and makes sure the amount that they are giving another bank matches the amount stated on the check. When they dont line up, the bank you made your deposit with can come down on you.Source: I used to work in the adjustments department for Wells Fargo.Human: Hypothetical question: what would happen if I didnt catch the mistake and spent the money, what would happen?  <response>: Most likely they put your account into the negative and would give you x amount of time to to cover the difference.
