This was true in Poland until the interchange fees got capped to 0.3% where they are now... now everybody accepts cards. But here in PA I see more and more places put in credit card surchages - I yesterday upon visiting a local pizza place, I noticed they have a sign saying "as of 6/1/19 there will be a 4% surcharge on all debit and credit card transactions." But along that came a new terminal with NFC acceptance.
