TULSA — Tom Coomer has retired twice: once when he was 65, and then several years ago. Each time he realized that with just a Social Security check, “You can hardly make it these days.”
So here he is at 79, working full time at Walmart. During each eight-hour shift, he stands at the store entrance greeting customers, telling a joke and fetching a “buggy.” Or he is stationed at the exit, checking receipts and the shoppers that trip the theft alarm.
