That’s what it’s become, but it’s also an easy way to get in and out without talking to anyone if you aren’t dumb as shit. If understanding how a cash register works is so hard we should be paying the workers who do so much better and giving them much more respect. We really should anyways but that’s a different issue.
Corporate initiatives to reduce workforce by misusing technology isn’t the fault of the tech itself. Which is incredibly easy to use, or at least I haven’t ever had an issue that wasn’t the result of another customer over the entire time self checkouts have existed
Edit: to be clear I’ve watched people struggle with them long before giant retailers decided to get rid of as many human cashiers as they can, that is fucked up and I hate that as much as y’all do, but that isn’t the fault of the self checkout system that was originally supposed to alleviate traffic by allowing those only buying a few items to bypass the lines
