I was thinking about infections in regard to cosmetology. Nail fungi etc, I wouldn’t trust an unlicensed worker for practically anything. Isn’t the purpose of a professional license the fact that it’s a sign of professionalism and a guard against malpractice? A business screws up and their license to practice is in jeopardy.

An unlicensed cosmetologist uses unsterile materials and repeated customers get eye infections. What recourse do the customers have? Does the cosmetologist stay in business? There’s no license to lose.
