Slow blood flow?

I went and tried to donate blood today. I drank a lot of water, about 50 oz and ate a lot of food before I went. I have really small and deep veins, but they were able to get a vein to work. However, after about 5 or 8 minutes, they came over and told me that they would have to stop the donation (it was plasma) because it wasn't moving fast enough. They only got about 100mL/ Why does my blood flow soo slow? I do have poor circulation to my hands and feet

Update:

My blood pressure was 118/68 and my body temp was 97.4

    More than likely it was the small vein size, they have to be be big enough to carry a decent flow and the needle is pretty big: in a small vein it could be up against a valve or the wall easily, restricting flow.

    if you have poor circulation to your hands and feet then you have poor circulation. Did you tell them that when they went through the stupid questions? Because you're really not supposed to do it if you have any kind of heart problems.
