Using the scan-it-yourself check out lines is not one of my favorite things to do—for a variety of reasons that I touched on in previous posts. If we have no produce and just a few items, we sometimes use them as we did recently in Wal-mart.
There is always a hand-written sign on each register indicating that gift cards cannot be used at the scan-it-yourself register. There was another sign also posted on one or two of the registers recently. It stated, “Cash Cannot Be Accepted.”
Writers of science fiction usually describe a future when cash is obsolete. Will my paper money go the way of phone booths, surgeons, and landlines? Sometimes I feel like I’m living in the future; what next, the Jetson’s will move in next door?
