Harry Flagg worked at Manchester Airport for over twenty years as a cleaner, including a long stint in the VIP suite. Having visited the Rovers Return Inn and commented on how "unclean" it appeared, Harry agreed to clean it for a few pints of beer and £10. Having made such a good job of it, landlord Fred Elliott took him on full-time. Soon Harry became potman and cellarman. He also cleaned at Underworld for Mike Baldwin, saving businessman Preston King from a heart attack at one point. He clashed with Frankie Baldwin when her husband Danny took over as a shareholder in Underworld, she teased him and labelled him 'Half Mast' referring to his surname.
