It seemed rare 3-4 years ago, but now Kroger, Publix, Walmart, Target, they all have ~6-12 s/c registers, sometimes at each end of the store (often so far apart a line forms at one, while the other remains empty). There seem to be a lot of cashiers on weekends, but fewer overall. So many unused lanes, most of the year.
