Kroger review: double car carts

I shop at the north bend road location, and every time i go i have to use a double cart, because i have twins. I have had to clean leaves, and always have to dry cart off. It's not because they are in the cart corral, but because they put them outside. As a parent of twins, i don't have the time to dry or clean the cart before putting child in. Other stores keep these carts inside for the convenience of their customers. At this location, they are kept outside. What is the sense of having them, if you have to clean or dry them?
