Some criticize the "Just Walk Out" system because of the reduction in manpower in stores. However, Amazon said in a blog post that the technology will allow Whole Foods employees to carry out other work in stores. The company, furthermore, said, “With Just Walk Out-enabled Whole Foods Market stores, how Team Members in the store spend their time is simply shifting, allowing them to spend even more time interacting with customers and delivering a great shopping experience.” The system should therefore improve interaction and communication with consumers.
