<prompt> Human: We were at a restaurant with another couple a month ago and split the bill. I just saw on my wifes credit card statement that when the restaurant split the bill, they swiped our card twice so we ended up paying the entire bill. Our friends signed one receipt and we signed the other so I never could have known unless I was monitoring charges in real time, etc... Is there any real leg to stand on here with the restaurant? Is the restaurant liable and is it even something you would win on dispute? Its a local restaurant so Im not sure, unless its clear that they are at fault, that Id raise a stink regardless so mainly curious what are the options here. From a friend perspective, the 120 this cost me works itself out over time in my opinion given that they entertain us quite a bit at their house, etc... so I wont be going to them to ask for the money if thats the only other option.x200B;x200B;  <response>: Did they swipe your friends card as well? If yes, then you need to work this out with the restaurant. If no, then you need to work this out with your friends.
