Correct. For example, at Isaac's Hostel in Dublin (where they were aware of DCC and happy to help me avoid it, acknowledging it was a rip off), I said to her when handing the card "charge in EUR, not USD" and she said no problem, just hit "NO" when it asks "amount OK?"
Here is how it went:
She inserted the card (reader on her end)
PIN pad popped up "US$XX.XX Amount OK?"
Hitting no caused the transaction to proceed in EUR
How the f*** is that "active choice" as the networks require? It's worded so that you'd think the option is yes or don't use the card. Nothing about the prompt indicates that no results in an EUR transaction.
