In another section, SE reader jo_wang mentioned using those self-service check-out registers that a popping up in a lot of grocery (and other) stores. Do you use them? Or not? What do you think about them. Personally, I am not a great fan (How about: They Suck?) I've had some bad experiences. I never use them if I have any produce of by weight items. If my order is only a few packaged items, maybe in a pinch, but I do not like them. Please share your thoughts.
