Well the gas stations have a "cash price" and a credit card price, however remember that the pumps control the sales. If you start rquesting cash think IRS AUDIT!! Better idea, talk to your cc company about reducing your fees, as much as they can based on Visa/MC fee control. I love my Discover card which is why I accept that from guests, and I lost business when I was not taking Amex. In fact unless I take a huge amount of Amex, I pay a flat fee/mos and it works out cheaper than Visa/MC..
So you accept Discover Cards? Is that expensive? How do you get to have a flat fee with Amex?

Discover costs me the same as Visa/MC - just call Discover Merchant services. Love them. Never had an issue. They don't increase the base rates like Visa/MC, which are then passed on by the processor.
I pay Amex $5.99/mos when my processing is below a certain $ amount. I can't even tell you what that ceiling limit it, after the first time I lost a business guest when I could not accept their Amex card, I changed my tune. I also had a local hospital put their temp ER doctor with me about 30 nights over the last 2 months, had I not accepted Amex they would not have put him with me.
If you are paying more than 1.59% Qual tran) with your Visa/MC cc processor, renegotiate ... just don't go to a new company if you are under contract or they will hit you with cancel fees. You should also not be paying more than 0.15c per transaction.
If you can process as debit cards (pin pad needed, that's about the best way to go - costs you about 0.67c per tran, that's it, but they are not always the best method for hotels.
