A clinic for women

Hello, I recently went to A clinic for women at Mt Alvernia Hospital. A few red flags I felt and would like to get some opinion. 1. Cash only for non supplements - we had to withdraw hard cash for consultations, test and scan payments. But they allow credit card payment for supplements. 2. Clinic staff can prescribe supplements to patient without doctor presence. Is this allowed? Not sure if I am thinking too much.
