Mrs. Majuki and I were at an outlet mall in Taiwan, and I saw my first case of DCC on a tap transaction at the food court. The cashier asked us which currency, and we said TWD. The cashier helped Mrs. Majuki select TWD. I couldn't see the exchange rate from my vantage point, and the cashier opted us out quickly. The pending transaction amount is the Visa conversion rate, so I was unable to tell what the DCC rate was.

It's unfortunate that contactless no longer offers a certain way to avoid DCC. Others have posted here as well, but this was my first experience.
