Also, the last time I went to a cashier, because it was the one time I saw a long line at the self-check lane, I stood in the short line, I was third, while the cashier chatted up the customers, left the line to help another cashier with something and was generally very slow. I suspect they’re not required to be efficient anymore, and perhaps even encouraged not to be. I watched as the guy I would have been behind in the self-check line left the store while I was still second in line at the cashier.
