omg haha!! I realized that too, that's hilarious. This really nice older gentlemen came in and he had no idea how to work the things so I showed him and I was all "I think it yells at you if you tap it now" and I tapped it and sure enough, the computer says "please scan an item to begin!"
I also think it's really funny how every time it prints a receipt the software has to remind the guest to grab it, and it's not very quiet about it.
