If you find value in it, that's fine. I not only find value with interaction with the lovely checkout people, I dislike the cost of scanning and managing the items during checkout being my problem so a huge company can save money. If they were to implement a discount as a way to say "we'll pay you for your work to give us your money" I would consider it.

That's not to say the value of the convenience is never worth it. I exclusively use Sam's Club scan-and-go because the time I save is much larger than the publix/walmart/ect.
