And the setup you described is unlikely compliant with Visa/MC DCC implementation rules. I have seen the "are you sure?" prompt in the past on an ATM, but I forget where that was.
At least this is unlike some implementations in China where there is no DCC prompt at all. The terminal just DCCs you.

In one scenario, a merchant literally saw me hit EUR and I told him EUR please and then he grabbed the machine before the second prompt and out popped a receipt with DCC on it.
I know you used quotes around mistakenly, but I wouldn't give any merchants the benefits of the doubt when it comes to DCC. I hope in the above situation you either had the merchant void and rerun the transaction without DCC or promptly disputed the amount.
In the future, I am likely to file complaints with Visa or MC, depending on which card I use, since it appears that they've been following up on merchant complaints with surcharging. I imagine that they might follow up with a DCC complaint as well.
