<prompt> Human: Bought gas and 20 cashback. Cashier handed only 18.25 back and said there was a 1.75 fee for cashback. Is this legal?  <response>: Ive never specifically heard a law against it, but I would imagine that they have to tell you what the fee is before you agree to get cashback. Cant just be likeoh btw Im gonna take some of this. And I would think it wouldnt usually be subtracted from the cash back amount, but added on, like a fee at an ATMEdit: as a side note, I would personally choose not to do business with any merchant with a policy like that
