Self-service is a mixed bag. Yes, I like ATMs and Netflix (or Redbox). But I hate self-service at grocery stores especially if I'm buying produce etc. I'm not a big fan at home improvement stores much of the time either.
On the other hand I was listening to a podcast when I popped into boots to buy lunch. Fairly busy so there was a queue, I drew the short straw and got directed to the legacy kiosk. This means having to pause what I was listening too, lose concentration, and switch into conversation mode for no benefit at all.
Ikea is simply far easier to self-scan. Back in the olden days you could scan your shopping in the supermarket as you put it into the trolley. Rather irellevent now when nobody does a "weekly shop" in person any more but far better than the "put into conveyor". Go back far enough and you used to have to ask someone for every item you wanted, no self picking.
While your comment is hilarious, i still think if cashiers at supermarkets weren't a thing that would make for a MORE enjoyable and healthy environement to interact with our peers
One of the problems with grocery stores specifically is that I buy a fair bit of stuff that isn't bar-coded, especially produce. I also guess that I'm not so much into sticking earphones in when I'm out and about. (And I also do a sort of weekly grocery shopping when I'm not traveling; no especially good delivery options in my area and not sure I would routinely use in any case.)
Funny; in more than one supermarket here, you're supposed to weigh the produce yourself using one of these[1] before getting to the register, even before the self-service checkout appeared.
Self-service checkout in any form is pretty much a good reason for me to avoid a store/chain unless they were really compelling in some other dimension.
