Yeah, you just raise prices 10% and pocket the difference when people end up having to use more cashiers because the self checkout is too full from fools thinking they are getting a discount. It's no different than all the stores with 'reward' programs where you get cheaper or better prices. They track everything you buy and sell it, making more than the amount you are saving. Seems better to recognize that automation of things like checkout is here to stay and incentivize alternative methods to keep people you know, fed, housed and alive.
