see my answer below.I guess it's not quite the same thing. Self-service checkouts are just a way to buy your groceries — same with online shops. In both cases, the human is (or was) mainly there to help sell a product, not to deliver a service in the proper sense. Sure, you could argue that it’s still a form of service, but the core business of a company like Walmart isn’t about providing human services — it’s about selling goods.
