People-who-come-to-my-store, you are mistaken in thinking I am your personal cashier. Girl-next-to-me is not your personal cashier either. Please do not come through my line with two cartfuls of things and then end up with twelve (yes, count them, twelve) carts by the time you leave. Please complete your shopping before you come to my line. And also, please do not tell me that things are ninety percent off when I work here and I know that they are not. Do not take up my entire morning with your meaningless drivel!
I will smite you. Smite you with the wrath of Sauron.
