> My understanding is Europe caps the interchange / card fees that credit card companies can charge merchants. Not sure, how strongly this applies. I frequently get denied(verbal denial that Amex doesn't work, use something else!) when I pull out my Amex in stores(random Tedi/Lidl/Aldi but not all), so now I usually resolve to ApplyPay(cashier don't see the card and can't ask to use some other card). If it is actually denied by the machine, I use a different one, no harm done. One particular small cafe told me, Amex charges are too high and cost them more than Giro/Visa/MC. Some places are also very adament about using a "Debit" only Visa/MC/Giro!
