Heh. I first encountered this story on NPR (it was involved in one of the questions on Wait, Wait, Don’t Tell Me). Shortly after hearing it I stopped at the supermarket and…
No, I didn’t happen to have a rage-inducing encounter with one of the self-checkouts there that day, but it sure did put me in mind of some past infuriations.
Well, I almost had one of these at a supermarket once. When I go to the store I bring along a large canvas bag to carry my groceries home on the bus. Every so often I use the self-checkout, which occasionally has a problem with me putting my bag on the “post scanning” area so I can place my purchases directly into it. Apparently the weight of the bag makes it think I’m trying to bag something without scanning it. Usually it eventually stops asking me to please take the item from my (empty) bag and scan it, but once this took several minutes of removing and replacing the bag. I guess the scale was extra sensitive that day.
