How do you get your Zzzzzzzzzz's?

I was in CVS today, and an elderly woman cashier was ringing up my purchase. She asked, "Do you have a CVS card?" I replied.....yes I do. I looked in my wallet, found it, and looked up and her eyes were closed. I prompted her. Miss? and she opened her eyes. Damn! napping at the cash register. She is probably 65 years old, if that. I want to go, shop, and get the hell out of there. Come to think of it, sometimes the younger workers aren't much better. How do you get your Zzzzzzzzz's??
