Getnet and the Ethiopian woman who's name I do not know, despite there good work they were both were very unprofessional. I left a $2 and Getnet started talking under his breathe criticizing the tip. My wife also left a $2 tip and the Ethiopian woman chased my wife down and gave my wife the tip back stating that she works hard and a $ 2 tip was not adequate. Never again will I get my Shoe's Shined at the Charlotte Airport!
