Man banned from all Walmarts for life

'Good Morning America' reports an Arizona man is now banned for life from Walmarts worldwide. Joe Cantrell said he was trying to get a price matched at the store, and an associate told him it wasn't allowed. He complained to management and left. When he returned a few days later, Cantrell was handcuffed and charged with threatening, intimidation and disorderly conduct. KTAR reports that a Walmart spokesman said the associate felt threatened.
