<prompt> Human: I have a William Hill pre-paid card which I can use solely for sports betting and the easiest way to retrieve my winnings is by using an ATM machine at a nearby 711. Last night I went to withdraw 80 and the machine gave me 160. I got a receipt with the transaction and on the receipt it shows that I withdrew 80. I also checked my online account and it also only shows an 80 withdrawal. Am at risk of anything if I keep the additional 80?  <response>: Theres a good chance your account would get hit with that 80 later down the line. Talk to the bank that owns the ATM and tell them what happened. Better safe than sorry.
