CHARLOTTE HARBOR — Kim Casey, the owner of Morgan’s Cafe, fought Florida Power & Light over some $3,000 the power company said she owed because its meter had been undercharging her for years — and both sides came out a winner, she said Friday.

Casey said an FPL customer advocate who worked to mediate negotiations between her and the company over the past few weeks notified her Wednesday that FPL had dropped its claim to the retroactive charges.
