I’m seeing more and more of those “self-checkout” units at the local stores. They always creep me out a bit. There just seems to be something really weird about the idea of walking up to a mechanical box, shuffling around my own transaction, and then leaving, going out of a store without passing by a person.
I feel as if I owe somebody some kind of explanation, like “Here’s my purchase, and here’s my money, and they match up; so don’t call the cops.” And then this person is supposed to give me the nod, like, “Okay, you’re alright this time; but when you come back, we’ll need to see each other again.”
