Trips this month
Sydney and Brisbane (not using my AUD cards due to exchange rate): DCC exclusively encountered on ANZ chip and pin terminals, press CLR to avoid.
Wakayama (Kansai), Japan: I don't think we were asked to charge in HKD throughout the whole trip.
Seoul: Lotte supermarket offered a choice on the signature pad, very clear. Two upmarket restaurants also offered a choice, one also on the pad and another one by operator input (the waitresa came back to specifically take our selection).
