What IS it with Walmart and the carts that pull, stick and wheels that squeek and wobble? It takes me more time to find a cart that won't pull my shoulders out of joint than it does to shop. Why is the human food on one side of the store and the pet food on the other side? I dread going there but we only have two grocery stores in the small town I live in and SuperWalmart is one of them. UGH...and owie.
