I went to Wal-Mart to pick up a prescription (for my ridiculous sinusitis!) and noticed how amazingly quiet it was in the store. At first I couldn't put my finger on the strange lack of noise, but as I got my cart, wary as I was because I ALWAYS get a bad one, I noticed that it was brand new! No large dents in the wheels, no gum or string wrapped around them, and remarkably clean! I looked around and realized that ALL of the carts were new. The silence was the lack of clanging carts or squeaky wheels! Who knew what a difference that would make? I actually had a pleasant shopping experience there, probably mostly because I kept marvelling at the quietness. Way to go, Wal-Mart!
