Where there's a helpful smile...
If you're an observer with attention to strange details you can make a trip to your local grocery store or large discount shopping chain an entertaining experience. I went to our local Hy-Vee food store (the famous one where St. Louis Rams' MVP quarterback Kurt Warner used to work) and, among other things, noticed that when you check out the first item shown purchased on your receipt is the name of your cashier, and the price is $.00. I wonder if Christie K. knows I bought her for nothing?
