Walk the whole market end to end — buy nothing till the far end

One lap, gate to gate, and nothing goes in your hands on the way — not the first good thing, not the second. Every stall gets one chance to pitch you, and most of it won't survive the walk. Whatever you're still thinking about when you hit the far end is the thing you actually wanted — walk back and buy exactly that. The grilled thing at stall three will test you; that's the game.
