Near the corral doesn’t take a lot more time to pick up from in the corral. I agree that leaving then in the corral is fine, someone still has to pick them up from there. But leaving the cart randomly outside has the potential to cause issues for others, completely ignoring the business owner.
You are right, I was being a bit hyperbolic. It’s equivalent to picking stuff up off the shelf and setting it on the ground. No damage to the product and would take workers more time to pick it up. Might as well start doing that every time you go to the store.
