"Say no to trainees"

I spent some time at the end of January in East Surrey Hospital, but the worst part of it all was in the A & E dept. a young male trainee was asked to put a cannula in my arm. He tried 6 attempts and still could not do it. In the end he panicked and started stabbing at my veins!! It was truly very disturbing and actually put me into shock. I am not great with needles anyway and think it would have been fair if he had asked me if I minded that he was only training, it would have given me the option to say no!! He should be supervised before he is let loose on patients!!
