“ The added benefit is that the carts sitting outside have been able to be somewhat disinfected by the sun during the day.”
Lol my thoughts exactly!
I also grab stray carts outside to push in to the store because the sun and fresh air help sterilize the carts. No other reason.
And when done shopping I return the cart to a corral because we have no flat parking lots here and the buggers want to roll away and wreck into vehicles.
