Thank you to clarify. Then why did you write "just"? In one reading, this is slightly dismissive. In retail spaces, cleanliness and tidiness is very important for the shopping experience.
I disagree that it matters beyond sanitation, although I admit that’s a matter of preference. In any case, it isn’t life-or-death, environmental catastrophe level stuff.
You apparently didn't live in the U.S. during the late stages of K-Mart's existence. K-Mart was a major discount retailer, locked in a years-long battle with Walmart. But in the years before it finally went under, many stores (maybe all?) were plagued by messily stocked shelves, unattractive merchandising, stock pulled onto the floor and not picked up, dingy flooring and poor lighting. I'm not talking just the toy section, but the linens and other dry goods. The stores in my area were simply unpleasant to shop in, so people stayed away, and the whole company went out of business. There are certainly issues with Walmart as a company and employer, but in my experience their stores are well-maintained, the merchandising is decent, and the shelves are neat.
I both A) don't believe you at all (would you rather shop somewhere you can easily find and access the product you're looking for, or where you have to track down an employee to dig through the clutter to find each item?) and B) feel we should note that Walmart's "ideal shopping experience" is not the same as the customer's. They want you (in the amalgamated, averaged sense) to traverse the store in a certain way, to select the right items, to be enticed to buy the other right items, and to leave without encountering so much friction that you decide to go to Target next time; those subtler effects are absolutely affected by organization and aesthetics.
I don’t believe that you don’t believe me, and I don’t think either of us will be able to present a compelling argument about the beliefs and preferences bouncing around in each others heads.
