Historically (like, 15+ years ago when I did the SEA backpacking circuit) there have been some cards with ridiculous fees for international transactions. Like, a flat $10 per transaction. Back then when I saw prompts like this on card terminals I assumed it was targeted at those cardholders (or people who had heard stories of those and were unsure and worried what they would be charged and wanted to be reassured by a number in their home currency)

Just so everyone is aware, it is still considered a foreign transaction regardless of which option you pick. So if you are using a card that charges for that, then you will be charged a foreign transaction fee. It is a foreign transaction fee, not foreign currency fee.

Except American Express, which does have foreign currency fees (on some cards).

I think that’s exactly a big part of why this scam was developed. If you aren’t that informed, don’t know your credit card terms by heart, but you’ve heard about those “foreign fees” it’s very plausible that this service would save you money. Not likely of course, since the scam is obfuscated and hidden in a dollar amount presented without the computation.
