America's biggest supermarket chain is seeing signs that U.S. shoppers are getting nervous about the future.
"It's fascinating right now from a customer standpoint. They feel incredibly good about the economy but very nervous about where things are headed," Kroger Co. Chief Executive Officer Rodney McMullen said in an onstage interview at the National Retail Federation's annual trade show in New York City.
"If you talk about questions in the present," American shoppers feel just fine, but "if you change the question a little to 'where do you think things are going,' there's a lot of uncertainty," he said.
