DCC at restaurants / retailers / hotels have been in practice for over a decade.

We first saw ATMs displayed the DCC traps were 4 years ago in Turkey, from Turkish banks in Adana to Societe Generale at Bodrum. Since then it is much wide-spread. Always read the screen carefully and always opt for Decline Conversion. A few weeks ago we saw the BNL d'Italia ATM in Bologna display the DCC option screen. BNL d'Italia is owned by BNP France fwiw.

Recently I read about the ubiquitous Blue Euronet ATMs do not give such option but DCC you without any warning. These ATMs are very easy to identify, they are stand alone, display the Euronet name and logo. in Blue and Yellow design.

Avoid the stand alone ATMs and always use one that is either next or inside the foyer of a bank - this has an added advantage - should the machine eats your card, you have immediate recourse if it happens during the banking hours.
