Now, we have a guy without a shopping cart coming up behind the woman, and he wants to pass by. But we also have a woman and her two kids beside her, with a shopping cart, coming from the other direction, trying to pass the guy.

In order for the guy without the cart to pass the woman at the same time the lady with the two kids is trying to pass the guy with the cart, they all have to go down the middle of the aisle, facing each other and passing each other in VERY close proximity. As in - bumping shoulders.

The one-way scenario REDUCES this. It doesn't eliminate it, but it does reduce it.

You won't have people coming within inches of each other, while facing each other, in order to pass the people in front of them.

You'll still have people trying to pass, but it'll be a single lane of "people trying to pass" right down the middle, instead of people coming from both directions trying to create two "passing" lanes in the middle.

One passing lane vs. two passing lanes, all taking up the same amount of real estate.

Reduced risk. That's what it's about.

Good grief. Nonsense. This is lunacy.
