I deliberately use the manned checkout, because I'm human, and I believe in helping out other humans. That seems to be a "quaint anachronism," these days, but it's the way this old fogey was raised.
I know that someday, I won't have a choice (Home Depot only has cashiers for contractors, nowadays, so I'm forced to use the auto-checkout), but, where one is given, I take the human.
Sometimes, I chuckle, as I go through fairly quickly, and see the long line, waiting for the auto-cashiers.
It's obvious that the only benefit comes to the company. If you aren't just getting a candy bar, then the auto-cashier tends to be slower (mainly because I am a lot slower at that stuff, than the cashier).
Drives me crazy watching people ahead of me try to do this. If the transaction hasn't been completed what precisely do they or indeed you think you are paying for again like handing the store an electronic blank check? I agree to pay...whatever the total ends up being!
Yeah, it's "trusting" the store, but it has never resulted in unwanted charges. I do it for the person in line behind me. I can afford it, if there was to be an issue, and the service desk is about ten feet away.
In Japan, they make a ceremony of giving you your goods before accepting payment.
Just hit the 'I need help' button on the self-checkout and an employee will show up and you can ask them to ring up your items.
The reason that I insist on using the manned lanes, has nothing to do with being uncomfortable with the automated process (I know that it may seem that way, with my gray pompadour, but I'm actually fairly comfortable with tech). It's just because I know that the reason the store uses them, is to fire cashiers, and it's sort of a "stay with them until the end" kind of thing, in my mind.
Like I said, not really the way people think, these days. We tend to be extremely selfish. I participate in an organization that encourages us to adopt a mindset that takes other peoples' existence into account. It's really just symbolic, I know, but I do it for myself; not for others. I feel that symbols are important.
I don't understand why people do this.
