I had an awful experience with this system the last time I went to a Whole Foods. The problem was that there was insufficient signage explaining the system, and the computer announcer was quite vague about who should go up. When a register was free, the computer spoke “next”, not “A” or “D”; if there was a screen with the letter, it wasn’t easily visible. In fact, I didn’t even notice the tiny signs labeling each line while I was standing in line. As a result, when I was at the front of line “A” and the computer called “next” after the other lines had gone, I went forward, but another customer did too. The other customer ended up cussing me out for going ahead of him – it turned out he was in a “D” line that, from my “A” line, looked like part of the “C” line. Being yelled at for not understanding the rules of a poorly explained system made for a unpleasant experience.
