Are you serious? In the old days cashiers rang things up by hand and
they were usually so fast that you really had to keep an eye on the
register to catch mistakes. Now they have a fair sized screen that
shows the item, weight and cost per unit if applicable, and the price,
and there is room on the screen for about a dozen items, so it is much
easier to catch mistakes.
