I don't see where you're getting the impression that 1,000 workers are monitoring every single individual that walks into the store. The figure used was the total amount for the whole program (many locations), only one person was reviewing each case, and they were only even reviewing 70% of cases. Your argument is no different than saying that every time you go to McDonald's, you're entitled for expecting the hundreds of thousands of McDonald's employees globally to band together to make you your burger.
