I was at the Dufry duty free shop at YVR today, and I noticed on the screen that there was a post-it note that said <-- Only CAD covering the lower right portion of the screen. I did a contactless payment, which resulted in a DCC prompt, and the note covered the DCC option. The cashier proactively said, "Press CAD."
I don't recall there being DCC on a contactless payment about a year ago. Mrs. Majuki didn't buy anything there during our last visit in May.
I'm not complaining, but I'm wondering what the motivation was to be corralling people toward opting out of DCC. I'm wondering if it was more than just trying to steer customers away from a bad exchange rate. There are two reasons I could think of: 1) they had chargebacks for people who unknowingly accepted DCC or 2) it is easier to remit any necessary duty to CBP since this shop was inside the preclearance area.
