The DMV of commerce.
I've quit shopping at places that have self-checkout, such as Albertson's. I do all my grocery shopping at Publix, which has human beings at the registers. Many of them live in my neighborhood and like to chat, but they're very efficient and I enjoy shopping there.
I hate standing at a machine, trying to shove my stuff into a bag, being reproved by the machine if I hit the wrong key or do things out of sequence, etc. And incidentally, I'm not a million years old, I'm computer literate and I like things like ATM cards and direct deposit.
But the "self checkout" stinks. Maybe they should have one or two stations for people who like it, but they should also hire more clerks for the registers and be ready to call stockers and other people up front when there are lines. That's what Publix does, and it works just fine.
