most places try to hire hot girls to do the registers.
only place i have seen to consistatly hire old, ugly people to run them was Lowes. I worked part time as a cashier (loved the discount! fixed up my old house with it) and i swear all the people i worked with were old and ugly. except me. i was young..and ugly.
Ridiculously hot late teen to mid twenties checkout girls. You won't find them anywhere on the stock floor, but at checkout, smokin' hot. Don't know if it is pre-requisite or maybe they apply and that's all they're good for?

My local Menards also has a lot of young hotties working there.
You're just getting old and high school girls look hot to you.
If you were 16, you would probably be like "meh".
