Do you remember the procedure for refusing DCC? Did you have to press no/cancel? Were the terminals customer facing? It sounds as bad as Poland where the staff have been trained to get people to fall into the DCC trap.

As a side story, I found someone respond quickly, "Euro!" when offered at Harrods yesterday at LHR T5. In the customer's defense, if most of the customer's shopping is within the euro area then the person might be ignorant of DCC just like if you're coming from a larger country such as the US, Canada, the UK, Australia, or Japan. I tend to think people from places like Hong Kong are more likely to have encountered DCC in the past and respond appropriately. Pretty much everyone I talk to who's a seasoned international traveler knows about the DCC scam, but the occasional traveler does not. As I've said before, I've even have had a few people mention, "Yeah. It was great. I could pay in dollars!"

I am also completely shocked at the number of people still bringing cash and going to bureaux de change or even at the hotels. In fact, at one of my hotels the reception clearly stated, "I would recommend using a cash machine if it's an option as the exchange rate is better." They weren't small sums of money either! I simply don't understand why people don't withdraw currency on arrival, especially since there are options - at least stateside - of doing so without fees and a 0% foreign transaction fee.
