We’re always looking for new ways to help our customers save time, and these innovations are just the latest examples of how we continue to invest in our stores and bring greater convenience to customers,” shared Ray Korsch, a Walmart market manager, in an encouraging statement.

Switching out cashiers for new technology didn’t go as smoothly as Walmart had hoped. Instead of speeding things up, it seemed to cause more frustration among shoppers. Unfortunately, this move added to Walmart’s struggles with customer service.

Historically, Walmart’s customer satisfaction scores haven’t been very high. In fact, they dipped even further according to the American Customer Satisfaction Index (ACSI). Measuring how well major retail stores satisfy their customers, Walmart found its score falling from 72 to 71 from 2016 to 2017. This positions them low, just trailing behind Sears.
