When I go to the supermarket I go through a self-serve scanner to pay for my items. It's much faster than waiting in line. So yes, some consumers get benefits.

  Using a self-serve scanner means you work for free for the store.

    No, not for free, but in a voluntary exchange for the benefits of not having to wait in long lines or deal with the cashier.
