Tried Revolut at a Travelex ATM in a local mall in the US today and I wasn't DCC'd. The ATM did support EMV though, which I was surprised about; I had to insert and remove before it told me to stick the card back in. I ultimately didn't go through with the withdrawal because they wanted to charge $3.25 just to pull out $20.
Anyway, do they commonly DCC at their ATMs or am I remembering wrong?
