I meant American Express. Acceptance of Mastercard and Visa is fine here, but American Express used to be far behind and is now playing catch-up.

And for groceries in Amsterdam for example you're going to be searching for quite some time for a supermarket that accepts credit cards. They only accept debit, which is what 99% of the population has as their primary card. Of course everybody has a credit card as well, but that's mostly used for online shopping and things like restaurants, not supermarkets.

So totally different from the US where any supermarket accepts credit-cards.
