Recently someone in my Blogland mentioned or blogged about supermarket payment systems comparing manned and self-service tills. I think it may have arisen because of the superfast manned tills at Lidl and Aldi. I cannot recall which the person preferred but he/she was very adamant about it.
So far as supermarkets are concerned it all boils down to money. Fewer people = less cost = more profit potential. Lidl and Aldi have limited employment down to a fine art together with easily scanned bar codes and staff who work their socks off.
So far as we, as customers, are concerned a lot is personal preference. Going through a manned checkout is rarely fast. An aside - a wonderful irony used to be that one of the fastest checkout staff in our Coop was also one of the most sociable. People would join her queue just for the craic (Gaelic - enjoyable social activity). Sometimes other staff would be free. However, if you are in a hurry with a few items self-service is invariably the fastest way out of the shop.
So far as society is concerned our Coop (which I believe is the largest in Scotland) employs a lot of staff and is an important employer. The more self-service checkouts the fewer people employed.
Amazon has gone one further with a trial shop, in London I think, which has no payment facilities at all. You register your phone when you go in and as you put something in your shopping bag it is automatically charged to your card.
Of course the fewer the staff and the greater the automation the less attention can be given to 'confused' people (usually elderly) or the disabled who need help.
I do not look forward to a day of complete automation, I'll pay the price and help employment. Am I alone?
