Roz is non other than Jeff MacNelly's widow, Susie MacNelly. She runs her famous greasy spoon, Roz's Roost, where the rest of the Shoe gang spends as much time as possible avoiding work. The wisecracking street-smart redhead takes guff from no one!
Her only house rule is NO WHINING!
And if her diner had a motto, it would have to be... If I don't have it, you don't need it!
