Beyond adjusterjack's observation, how hard do you want to push this? Push too hard and you could end up without a job.
I may have missed something, but I don't see any state law restriction in Florida that would stop an employer from deducting a debt owned to the employer from an employee's paycheck -- and Florida is somewhat notorious for its weak worker protections. Federal law would still apply, so deductions may not be so large as to reduce an employee's compensation below minimum wage.
