I don’t mind it for a small shop but for a big shop it can be a nightmare. The queues build up & things are always bleeping or going wrong and then you have to stand around and wait for an assistant to come with their magic key, they often seem flustered.
Last Christmas my youngest daughter went into her local Morrisons with her partner and they did a massive Christmas family food shop, the trolley was piled high. When they got to the checkout there was no one on there and they were directed by a manager to self service which was absolutely ridiculous with the amount of stuff they had. I told my daughter I would have walked out and left it all but as she pointed out she was working over the next few days so was unable & didn’t want to have do the whole darn shop again. After complaining and getting nowhere they reluctantly put it through. Really bad customer service not opening a till in that situation.
On the whole I prefer shop n scan in Sainsburys or better still, for a large shop a home delivery, Ocado are usually very good.
All very different to when I used to go to the local Coop as a child with a list for my mum, there would always be some old dears sat there on the chairs provided putting the world to rights while the assistants ran round and got all the items and packed it all. It was more of a social event for folk in those days. Not many people would have time for that nowadays though.
