I understand there are often provisions that sellers can't charge a premium for credit card payments to make up for the commission so in places where creditcards are common EVERYONE pays more because of credit card commissions. While there might be special rules for taxis and while in the USA most credit card merchant agreements prohibit adding a surcharge for using a credit card, they do not prohibit giving a discount for cash.
