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.
I don't understand people that get upset and hostile at employees in these situations. When I go through self checkout I go in with expectations already set that it's very likely that at some point during the checkout process the machine is going to trigger an alarm and an employee will need to come over and override the alarm. It doesn't happen too often, but when it does my first reaction isn't to get all pissy and throw things at the cashier.
If you have no patience for this sort of thing, then go through the regular checkout. See if it takes longer going that route.
I think a lot of it has to do with that last part of your comment. The amount of times I've gone to the grocery store to find there's no register open other than the self checks or that there's 1-2 open at a huge grocery store with a 6-8 people in line for them and no self check line... People are being forced into self checking when they don't want to. These people are obviously going to be more easily upset by issues with the self check machines. Walmart in my limited experience (try to never buy anything there if I can avoid it) is the worst offender I've seen.
