If he kept the prescription form, how did she get it filled two days later?
Simple. She called the doctor and had the prescription sent to a different pharmacy.
You couldn't figure that out all by yourself?
Listen ...very carefully......I'll explain it again.
All she had to do was call her doctor.......(ya with me there?)......tell him what happened, and ask to have the prescription re-issued.
What part of that is difficult for you?
