I withdrew euros from an International Currency Exchange (ICE) branded ATM at DUB this morning, and the DCC offer was 14%. It was easy enough to opt out:
The ATM offered GBP and USD as well. I was curious about how it would do this and using what exchange rate, but I went through all of the options and was unable to see a way to withdraw anything other than euros with my USD denominated card. Has anyone ever used one of those ATMs that advertises the ability to dispense multiple currencies to get anything other than the local currency where the ATM is?
