One of the staff at our local Morrisons was off sick and they had no one to do it at 8.00 in morning so they sent us through the scan and pack- I have to admit I had a paddy and threw a loaf of bread up in the air.
They expect you to know instantly how to use them.
I love tech stuff so I just swiped them through as fast as I could then it all bogged down -light on and it kept saying something but my hearing aids couldn't decypher it,
The kind lady came up and explained you scan one then wait till green light came up then scan another - This is slower than manned checkout. -Then it wouldn't work after I scanned some wine - I told it I am 78 for christ sake.
Also like others I have no idea when or where to put the bags on scales. Another delay.
Fortunately the lady is back and checkouts are back and we can have a chat about the potted plants we have bought.
We are picky with checkout lady as some of them think it's a race to see if she can send them down quicker than we can pack them- At that point I stop packing till she realises I have let the pile build up
