In response to your question regarding debit card purchases, I think most businesses, if not all, charge an additional .25 - .50 cents per debit card transaction fee. The fee is most likely charged by the company the business uses to handle their debit/credit card transactions. These companies are making lots of money by charging customers a fee to spend their own money.
Ok so ik my sister works at arco but you have to ask the employees there. :)
