Just an an update to the response from AmEx customer service - they have explicitly said that DCC is supported and that the customer should be presented with a choice on the terminal at the point of sale. Really surprised by this response and it implies a big change (I think) to the merchant agreement and undermines one of the reasons I use my AmEx over other cards when travelling.
Car rental cos are usual suspects for Multi-Currency Conversion as well as Dynamic Currency Conversion.
DCC means you should have a choice and chose (or had chosen for you) card currency, multi currency conversion involves a merchant representing you've chosen to deal in card currency all along.
Hard to tell the difference when you didn't sign the actual slip (I assume this is a card swipe situation where some back office did the billing)
My suggestion is - if Amex suggests it's DCC, ask them to charge it back as if unauthorised DCC and use your Euro invoices for supporting. See what merchant tells Amex
