A patient with complaints about Dr. Derm's medical assistant demanded a refund on his co-pay, then threatened to destroy the doctor's reputation online. The patient returned a week later with worsening cellulitis, Dr. Derm refused to see him. The patient later became septic and he filed a medical malpractice lawsuit. What did Dr. Derm do wrong?
