For me it's not the cashier's fault, I'm just generally an antisocial and I've done it long enough that I'm faster than most of them anyway plus I'm allowed to do it how I want and since I'm the one actually paying there's a vested interest in it being accurate where when you're just customer X in line there's no incentive for accuracy for cashiers.

Sadly what I take out of this article, isn't the fact that self-checks are going away but brick and mortar stores that a whole are going away. That's what these big box companies don't tell you, Walmart specifically because I've seen it popping up. Instead of putting in new stores they are putting in stores that are essentially just only a back room warehouse and they only service online orders.
