Pharmaceutical sales representatives were the doctors' little wadded jackets. They basically took very good care of the doctors. Some good pharmaceutical sales representatives could act as cotton armors, job-transferring comforters, provided small towels, and could even be torn into cotton swabs…
Strictly speaking, it was not that pharmaceutical sales representatives could not leave the doctors, but the doctors could not leave the pharmaceutical sales representatives.
A thoughtful and capable pharmaceutical sales representative was like a full-time secretary for a doctor. Even if he left the doctor, he could still have a bright future ahead of him. Even if he no longer worked as a pharmaceutical sales representative, he could still be outstanding in every other service industry.
