The 1936 radio serviceman shown here is netting an extra five dollars is netting an extra five dollars for the service call, simply because he uttered the words, “any other electrical appliances in your home need repairing?”

The accompanying article, in the October 1936 issue of Radio News points out that no serviceman would sneer at an extra $5, but these words often reminded customers of other repair needs that had slipped their mind.

One serviceman noted that during a recent call, he was delivering a midget radio decorated with Mother Goose characters for the customer’s nursery. After installing the set, he replaced a belt on a vacuum cleaner, repaired a few frayed electrical cords and damaged outlets, and replaced an old iron with a new automatic model. “Most people prefer to have radiomen repair their vacuum cleaners and other appliances since dealers too often send out high-pressur salesmen to attempt to sell new apparatus when only the simplest repair is required.”
