Some Walmart employees say customers are getting hostile at self-checkout — and they blame anti-theft tech

This is a most excellent place for technology news and articles.
That's pretty hard to do if you live in an area that only has the one store near, and even then; would the multi-billion dollar company really care if it gets like $1200 less per year from a single customer?
As for your first point, you're right. If the local business scene is non-existent, then there's little one can do.
As for your second point, well, that's not the point. If OP says he hates Walmart so much, and he has a choice, then shopping elsewhere would be good for him.
Plus even if $1200 won't break Walmart, well, at least that's $1200 OP isn't willingly and reluctantly giving to them.
