Starting next week, all Ohio Kroger customers are required to wear face masks if they want to enter the store. Cincinnati-based Kroger announced the new policy on Wednesday, saying it will go into effect on July 22nd at all their locations nationwide. The company announced the change on the same day that Walmart, the nation's largest general retailer, said its customers would have to wear masks starting on July 20th. Kroger operates over 27-hundred supermarkets and multi-department stores in 35 states.
