I'm not being forced to go to self-checkout, I deliberately choose to do so wherever it's available. Choosing not to do so for the benefit of cashiers' jobs would be going out of my way.

To be fair, my experience with self-checkout does not match what I see in the comments here. It has always been faster than the regular check-out wherever I go.

There used to be a Fresh & Easy near where I lived some years ago that had zero employees in store. I just went in, got what I needed, paid at self-checkout, and I was on my way. Perfect shopping experience.

Edit: already mentioned somewhere else in the comments, stores used to have all products behind the counter and you'd have to ask the merchant for the products (there are still a lot of places like that). But people don't complain about having to do the labor of picking up their own products from the shelves. Because you grew up used to this new way of doing things and you find it normal. People just try to rationalize their aversion to change.
