Good morning grey skies here at the moment. May I’ve seen people using those hand held scanners, I sometimes use the self checkout , but I don’t really buy that much in one shop.
I use the self checkout quite a bit … it’s great for using up bags of small change but that’s about as advanced as I’ll get.
Had a lazy day, doing nothing, as you do on a Sunday and as I do as often as I can. 
My wife selects our groceries then gets them delivered at our door. Usually by ASDA.
