<prompt> Human: Im sitting at the bus stop and this woman came up to me and said can you cash a check for me? Ill give you 40 bucks to do it I dont remember what else she said but for some reason she couldnt use her bank so thats why she was asking me. I told her no because I knew it was fishy. I just dont know what exactly you can pull off by having somebody else cash a check for you.  <response>: They give you a bad check. Your bank doesnt catch it when you withdraw the money. You give them the money. The check bounces. Your bank withdraws the amount from your account. You never see the person again. You are out the amount of the check.
