Thanks for the above post. I have yet to be DCC'd in Australia in my 6 trips there over the last 3 years, but I imagine it does happen. I don't much like the credit card surcharge that some places tack on, but at least that's disclosed.

I'll be headed back to Spain in February, and so I'm wondering what the best practice is for there? Should I specify that I want to be charged in euros or refuse to sign if I've been DCC'd? I half expect places that don't do DCC will think I'm crazy for asking them to charge me in euros. "What else would we use? Pesetas?"
