Blood donation

I donated blood at Witbank blood center. Told the 'nurse' not to press the syringe into my arm after the blood letting was complete. She did exactly the opposite. Before she removed the needle, she pressed the needle into my arm to prevent bleeding. She hurt me like hell. It was quite unnecessary! I have donated more than 50 pints in the past and few if any did what she did. I will NOT donate at Witbank blood centre ever again!
