I don't think parent is claiming that the shop owner is trying to scam someone. But these prompts have been around for at least 15 years, I'm also sure about that, this isn't new by any measure. And yeah, also came across shop owners who don't know what it is about, and then you have to chose.

Makes sense that shop owners in non-touristy areas haven't seen them before, as you'll only see that when the card has a default currency that differs from the default currency of the terminal.
