oh no, let’s all hope that Apple never goes near anything Amex. Horrible network to be part of if you spend time with your feet off US soil.
I spend a lot of time "off US soil". I live in Toronto and Lisbon, spend time in Washington DC, New York, Tuscany, Paris and Barcelona and while there are definitely places that don't accept AMEX, those where I would use it like restaurants, car rentals and gas and often grocery stores, accept AMEX just fine.
