I like self scan, but only because I've been on the other side of the register. I can scan and bag faster than most cashiers who I notice go insanely slow. When I shop I am in and out as quick as possible. Time = Money.
That being said, I'm also aware that the concept of expecting customers to scan and bag their own items is hilariously unrealistic for a few reasons. Some customers are technology illiterate and can't figure it out. Put a graphic there illustrating it, and they won't see it like the rest of the visual aids they miss (prices, the item they want, the big board describing the return policy behind guest service, overhead signs, etc), then you have other guests that feel it's beneath them to scan and bag because that's "like totally your job, you silly high school drop out you" <-- yes ignorant people actually say/think that. And then there's the customer base that wants human interaction in case there are problems, or they decide they don't want something.
In reality self checkouts are for a small portion of the customer base but Target HQ wants to cut labor costs. lol.
