We were at a Sams Club today. They had 4 self checkouts. There were 4 employees there to help if someone had a problem. I have used self checkout at Lowe's a few time. Half the time I had a problem & needed help, so I do not use self checkouts anymore. In the 15 minutes we were in line to get checked out, I watched the self checkouts. Almost everyone had problems. The only people that did not have problems were ones that only had a few items.
So most of the time there was an employee at each self checkout helping. It seemed to take longer for people to checkout themselves than if there was a full time cashier.
To me it appears that the store is paying the same number of employees, but getting less for it. What am I missing?
