I saw a first the other day at the local Safeway.

No, not the self-service scanner technology.  It’s been in place for several years and was recently expanded.  But for the first time, I saw a line-up to use the machines while, at the same, the clerk at the express line was waiting for customers.

Now, maybe people didn’t realize she was free.  But maybe, more and more, people prefer to use the machines and scan for themselves.  Maybe we’re being that well trained.
