Doctors should recommend things that can help someone's health issue.
Dr Bob is in an appointment with Leslie, who has what may be a skin infection.
Dr Bob needs to finish this appointment because it is lunch time.
Dr Bob tells Leslie that he needs to have his lunch but can schedule her for a follow-up biopsy, to explore possible treatments.
Dr Bob tells Leslie to go home and just see if she feels better tomorrow.
Leslie is glad the Dr is doing what is needed to make her well.
Leslie goes home and doesn't get better because Dr Bob neglected to prescribe an antibiotic.
