Ending the 'I don't know, what do you want' loop
Deciding what to eat is a classic low-stakes-but-strangely-hard decision, especially in a group where everyone defers to everyone else. Writing down every option that's actually been suggested and spinning removes the back-and-forth: whatever the wheel lands on is dinner.
It also works well solo, when you're standing in the kitchen unable to settle on anything — list three or four realistic options (not fifteen aspirational ones) and let the spin pick for you rather than scrolling delivery apps for twenty minutes.
