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.
The definition is wrong. There's nothing "self" about them if an employee has to hold your hand throughout the entire process.
Perhaps they should be paying the customer with savings since they're saving so much money not paying a full-time checkout attendant per register. The customer is now the employee.
I don't blame them
Remember everyone. If you see someone shoplifting from Walmart, no you didn't.
