I actually go halfsies on the cart (well, when I had to use one, anyway). I'd close all the peripheral registers (RX, Sbux, Cafe, Service Desk) without it and i would use it when I went down the line and closed the regular registers. Our AP never said boo about it, so I guess it was okay. The one that was in my old store was great! Rosie, as she was so aptly named, would glide across the checklanes with ease and wouldn't make sudden moves. The ones in my training stores I have been in, on the other hand, suck. Can't turn them, and God help you if you had to stop short it would go with you.
