<prompt> Human: Ive been overpaid twice by my college job. Instead of getting my normal 12 an hour, Im getting 112. The first paycheck I cashed, because I wasnt sure what to do, and hey its money payroll signed off on.Its been two weeks since then, and nobodys talked to me.Today I opened another paycheck, and same deal. 1800 instead of 200.I havent cashed this check because now it seems like a reoccurring issue. What should I do? Tell them about both checks? Just the second? Keep the money and invest in bitcoin???  <response>: This was such an obvious mistake, and yet you cashed the first check anyway. Please be prepared, you will need to pay back the additional from the first check. You are not entitled to keep the extra just because they made a mistake.I suggest you come clean as soon as possible so you can hopefully negotiate payback terms that work for you.
