The Fidelity Cash Management ATM card reimburses ATM owner fees; if I read it correctly, they may charge a 1% foreign currency conversion fee. The Capital One 360 account doesn't add conversion fees. On that card, one may still have the local bank's withdrawal fees: in the town in Italy where I usually do this, UniCredit charges a fee and Monte dei Paschi di Siena does not.
To expand on JMichael's point about dynamic currency conversion, the screen may say something like "Do you agree that this withdrawal of €200 will be charged at $250 U.S.?". People may think that, by saying no, or pushing the discreetly marked "Decline" button, you're backing out of making the withdrawal, but instead it converts the withdrawal at the fairer interbank rate.
