There are self-service checkouts - this is a plus. Self-checkout counters don't work - it's a star. The queues were as they were. What prevents to open the second block with self-checkout counters ??? And not all goods can be pushed through the checkout. Oh, how angry when all the purchases have already been scanned and this is revealed ... the fact: the multiplicity is what is possible, but not integers (4.8m in the example). Automated automated but not automated ... Five for the idea. For implementation two))
