Timely, that this discussion has turned to Uber. Most of the discussion in this thread seems to focus on Asia, but my travels in Latin America keep turning up new instances of DCC creep all over the place.

I was just in Costa Rica and used Uber. My card was charged in USD despite being quoted in the local currency when I booked the ride. The charge on my statement was US$14, charged as USD. But it should've been around US$10.50 had the transaction gone through in the local Costa Rican currency and left for my card issuer to do the conversion. Needless to say, at no point did I have the option to select which currency I wanted to be charged in.
