Re: All the more reason to avoid self-checkouts
My local Morrisons has just done a significant refit, replacing all but a handful (at most 6) of their proper checkouts with a whole fleet of extra self service checkouts.
At most, 2 of the proper checkouts are ever open, leading to long queues while the majority of the self service checkouts stand idle under the beady eye of a supervisor with very little to do.
Admittedly, the new freezers and chillers were badly needed, but the disruption caused by moving practically every product they stock to a new location in the store, added to the longer waits at the checkout, is not doing much for customer satisfaction. Particularly since they still manage to be out of stock on several (different) items every time I visit. Perhaps improve your inventory management instead of buggering about with the checkouts and pissing off customers and staff alike?
Can't help wondering if the new self service checkouts are geared up for this age guesstimation wheeze. If so, one less reason to use them, not that I ever do.
