Walmart CEO Doug McMillon said stores could close if the rising tide of theft wasn't stemmed. Customers and employees blame self-checkout, which Walmart has increasingly relied on, for theft. Since McMillon made those comments, more than 100 Walmart customers and former and current employees have reached out to an Insider reporter to say the retailer must rely less on self-checkout. "They need to hire cashiers again and do away with so many self-checkout," Mindy Stanley, a Walmart customer from Ashland, Kentucky, said. Polly Kearns, a Walmart shopper from Gulfport, Mississippi, said the best way to protect against theft and make customers happy was to eliminate self-checkouts.
