When Marie Roberts Waters walks away from her desk at Dabbs, Hickman, Hill & Cannon, LLP on Dec. 31, she will have logged in 50 years and some change with the accounting firm. Turning 82 in March, Waters began working for Earl Dabbs, now retired, on Sept. 11, 1967. Reluctant to retire even now and with no current plans, Waters said, “When my sister retired from the sugar refinery, she said, ‘You’ll know when it’s time.’ At my age, I just feel like it’s time.
