The way this all works is the merchant pays a fee to process you CC and the bank splits that fee with you. Gas stations are somewhat smart about this in that they charge you more when using a card since they're paying more for the transaction. However, it's annoying to consumers to charge a higher price depending on payment method. Not sure why gas stations are the only ones getting away with it.
