We've just had a new Sainsburys Local open in Dundee. Generally very pleasant however the checkout layout is infuriating. There is a kiosk, with three manned tills, and a bank of six self scans next to it, with a shared queue entrance. Pretty normal so far. However the self scan is a little pen with only one entrance and exit, which makes it very uncomfortable to use as there's always someone looming right over you.
Tesco Expresses do this far better as the payment area is more open and the kiosk and self scans at the same level with cupboards extending the whole way. For this particular branch I think the Tesco Express L shape would work well, with the self scans down the windows leading back to the door.
