People are quite selective about where they get offended on this one.
Self-checkout for gasoline is apparently fine. I seldom hear people clamouring for a return of the full-service gas station.
Having someone pick, box, process payment, and deliver your stuff is in a near-sweatshop type of operation is apparently fine (i.e. Amazon).
And so is pushing your cart around a large supermarket to pick out your own groceries rather than going to a counter of a general or department store and telling someone what you want, as would have been done prior to the evolution of the self-serve supermarket.
But what's not on is to make you use a computer to check out and pay for groceries you've picked out yourself.
