The OP is objecting on principle but that principle will lose in the long run. Every business is out to save money and if they are smart enough to con their employees into doing the work that they paid staff to do they are brilliant businessmen.
One of the smartest techniques is Aldi's that require you to pay a quarter to get a cart. This allows them to fire all the cart round up people in the parking lots. And the patrons of the store gladly put the cart back to get their quarter back. Nothing short of brilliant! Surprise that more stores have not done the same. Then again this is a German company. Very smart over there.
Self checkout is here to stay assuming retail world even survives the onslaught of online ordering/drone delivery/etc.
Self checkout is cheaper, customers like it, and makes sense from a queue standpoint (generally is setup with lots of machines/"servers" and a single "queue"). This means that if one customer gets confused/stuck, the line doesn't get held up (as happens with traditional human manned checkout stands).
