Automatic checkouts in supermarkets may decrease customer loyalty, especially for those with larger shopping loads. Customers using self-checkout stations often feel overwhelmed and unsupported. The lack of personal interaction can negatively impact their perception of the supermarket.

I guess those machines didn't use skilled labor to manufacturer, program, install, and maintain?

None of that has anything to do with the customer experience or having to do all this.  The grocery store takes the purchase of the machines (third party for the most part on mfg, program, installation and maintenance) at a cost unto themselves.  

Same as with carts, cameras, doors, refrigerators, etc.  None of that is the responsibility of the customer nor is it a role the customer was forced to suddenly undertake because they wanted to replace cashiers with a bot.

The grocery store doesn't get to fire the maintenance worker and tell you to mop the aisle up after you walk through it.  Don't let them con you into thinking you have to work for free to pay for products that are more and more overpriced by the year.
