It works like this: as you arrive, each person places their phone facedown in the center of the table. (If you’re feeling theatrical, you can go for a stack like this one, but it’s not required.) As the meal goes on, you’ll hear various texts and emails arriving… and you’ll do absolutely nothing. You’ll face temptation—maybe even a few involuntary reaches toward the middle of the table—but you’ll be bound by the single, all-important rule of the phone stack.
Whoever picks up their phone is footing the bill.
[A brilliant solution if you have highly interrupted meals. My friends, family etc. have no issue ignoring their phones…]
