ass backwards in Kansas

I always feel like I have entered an alternate universe when I visit Kansas. For example, this morning I visited the local grocers, had about twenty-five items in my cart, noticed the self-scan checkout had nobody in it, and proceeded to start scanning my own items. A teller quickly ran over to intercept my attempt at self-service and started taking charge. Do I look old and feeble? Do I look sinister? I'm not sure why I received unwanted help, but I was a bit taken aback by an overbearing cashier in a self-service aisle. Much to my surprise, she was actually quite pleasant, and she did allow me to bag my own groceries and push my own cart to my car.
