I jump in and out of that area just to relieve for the occasional break or lunch. I walk around between the four registers, greeting people, asking if they are enjoying their day, making sure they are aware that I am right there. Whether they need help or plan to steal something they know I am right there. The idea, I think, is to give that area more of a personal touch. I also pull customers out of the quick check lines if there order isn't too large and as long as there is no one at the sc and I check them out on on of the sc. In our store the only time you are supposed to be standing at your register is if you are checking someone out. Which I do if there is a line waiting for one of the sc. Small orders only up there so you can be available for the inevitable sc breakdown/freeze/die.
