You are a pharmacist, not the local preacher. Your job is to dispense medicines as prescribed by a doctor. Don't like it? Find a new line of work.
Since when is a Governor's order tantamount to a Doctor's Prescription?
Since when does a pharmacist have the obligation to refuse a legit Doctor's prescrip? (other than a mistake)
Guess if the pharmacist did not believe in antibiotics, he/she could refuse to sell those as well.
