No blood today

Grrr! Despite attempts on both arms, I was not able to donate blood today. I'm really frustrated because I'm convinced that, just like the last time, if the first phlebotomist hadn't sucked, it would have been fine. The supervisor took over and tried the original arm and the other side, but never got in (just like the last time). It makes me mad because I always tell them that my veins are small, and I've had trouble before, but they never listen until it doesn't work.
