It's difficult to prove a negative. For instance, many of us often wonder if DCC is present in the US - it is - because there are few data points since the vast majority of people in the US are using USD cards. The one somewhat local place where percysmith and I ate in HK didn't have DCC, but that's one data point out of tens of thousands. The other two restaurants where we've eaten were outlined earlier in this thread and did have DCC, but both clearly had expat appeal. That doesn't take away from the fact that DCC can manifest in the most unlikely places. There was one clothing store in my wife's smaller hometown in Taiwan that had it even though the customers were all local.

I definitely expect it at duty free shops, hotels, rental cars, department stores, and restaurants catering to a foreign clientele, but DCC is not exclusive to these usual suspects.
