It’s funny because where I live there were even warnings to never give your card to the cashier back when they weren’t so popular. It was precisely because of some rare cases of cashiers managing to clone or charge the card during that moment. I, and most people I know, wouldn’t just hand in their card if asked. It just doesn’t happen here.
I have very bad memories with this dish. I hated it as a kid and was sometimes forced to eat it. 🤮
