Technology these days, has really advanced, from the old cash registers. Several years ago, we wouldn't have even understood what a barcode scanner was. Today, it's become increasingly upscale in many of your large supermarkets. I've gotten to the point that I'd rather, go to a "self serve" register, than mess with the clerks and their attitudes. Even then the scanner, is equipped so that it can cause you to wait for assistance. I guess with every new thing that's being developed, there are always draw backs.
