I feel like this is getting worse and worse. Usually HK and Taiwan is not too bad about DCC but I've noticed almost every credit card slip I used had DCC. Even if the cashier specifically said they are charging in local currency, I still see the DCC amount on my online activity. I've been putting in several disputes a month for small amounts for DCC, and I'm sure the CC companies are getting annoyed as well as I think they still have to review each case manually.
