Who is Frank Menken from The Rocky Road to Romance and what is their importance?

Frank Menken works for Steve's radio station, WZZZ, as the regular traffic reporter. However, in the introduction to the novel, Frank hits a garbage truck and breaks his leg. Daisy fills in at traffic reporting until Frank recovers. While Steve admits that Frank's reporting is more professional and informative, he also comes to enjoy Daisy's fresh take on the job, which, though less helpful, is more light hearted and feeling.
