I think maybe it's pointless in the sense that the average shopper doesn't think it influences them. Statistically, it does, but they may not feel like it does.

It's still shitty, regardless of how effective it may appear. There's a reason the common items are always spread out, as I'm sure you know. Can't have someone grabbing milk, cheese, eggs, bread, and fruit all from the same section, then they'd miss the donuts and the cakes and the frozen pizas and the 'managers discount' almost expired meat section (I like almost expired meat, I'm poor too, but still)
