Just got DCCed at Lavo Jazz Bar in Shenzhen - they had Agricultural Bank of China machines and the DCC was automatic - nothing showed up - you signed on the screen and it was only at the end when the receipt was printed that I noticed after leaving that the DCC verbiage was on the receipt (place was too dark to read the fine print) and in any event I had already signed. Will be fun filing the Reason Code 76 complaint now.
