<prompt> Human: Im 18, just started my first ever retail job previously made drinks at a coffee shop, and i was the cashier today all afternoon. Today at work this well dressed guy spent 275 on a jacket and perfume. He asked if we did gift recipes, i didnt know so my coworker told him our store doesnt have them but the person the gift was for could just bring it back and do an exchange if they didnt like it. He went through with the transaction anyway. While i was bagging his stuff, Instead of swiping his card he input it manually and it went through fine. He signed the receipt and i stuck it with the rest of the receipts for the day. Later he came back and he wanted to buy a gift card for his friend but told me straight up that he spent a lot on gifts today and wasnt sure if it would go through. It got declined, and he tried another card that also got decline, so he just left. I went to my manager because i wasnt sure how to deactivate the card that he was supposed to buy. She told me if he came back to either get her or to ID him first. Now i am super paranoid that his first purchase was a scam or something, especially since he keyed in the numbers and i didnt know that that was controversial in retail until i started looking into more about this situation since i got home since it has been bugging me. Im so nervous and anxious now that i possibly messed up big time at work. Do you think i will get fired if it was a scam? Was it a scam if the card did go through but he could have later maybe just reached his limit and it got declined? Would he even bother asking for a gift recipe though if it was a scam? What do i do? Do i just hope nothing happens? Now im thinking too that when he signed the receipt did he actually write his name or was it just like a scribble or something? I mean the manager already knows he was kind of shady after i told her about him trying to get the gift card and his card being decline. What do i do here?Edit: when i say he manually put it in, i mean that instead of swiping the card through the machine, he just keyed in the numbers  <response>: Im no fraud expert, but sounds like something the store should worry about, not you. If you need to know it, its a training issue. And... receipt.
