I think the responses you are getting here indicate you should consider changing banks for your cash transactions, if you do enough foreign travel to explore finding banks that will cash AMEX travelers checks for free.

Like others, I haven't paid a fee for my ATM withdrawals, except at a couple of private ATMs in Canada. Thats on every continent but Antarctica.

I haven't been to Greece, but on July 1 a €100 withdrawl from Bank of Ireland at SNN posted to my account at $135.50.
