You love them? I avoid them like the plague. It’s like having to bus your dishes at a restaurant — like doing their work for them. Plus, the checkers are always over there helping people, because they don’t work really well. Or folks cannot figure out the commands, etc. There are too many variables — works great for straight-forward items, not so great for little things, odd shapes, etc. I do not like them at all.
I just got home from a store with four self check outs. All four were waiting for assistance.
