Sue (my ex) and I used to go together, it took them simply ages to find her vein and extract the amount they needed, usually by the time they had got her needle in the right place (sometimes hanging half off the bed) I was done.

In fact I was once called a "fast bleeder" by the nurse and I wasn't even chatting her up ;D

I always had a feeling of superiority when she was still laid out and I had finished my tea and biscuit - not that I'm competitive or anything
