a "vein" to pick

So you know the old expression "I've got a bone to pick with you"? Well I altered it a little. What the heck is wrong with the Red Cross? I went to a blood drive today to donate a pint of my hard-earned blood and I had rude interactions with 2 Red Cross employees before feeling remotely welcomed or appreciated. The first interaction was with the "I'm going to prick your finger and ask you forty personal questions" employee. She didn't communicate with me. If she wanted me to move my arm, she would man-handle me rather than using her words. She asked me to remove my long sleeve sweater so she could examine my veins. Her reaction to my arms was very discouraging. "You've donated blood before?" She asked this in such a way as to imply that this was preposterous ... "with those veins?" Yes, I know my veins are small, but they are pumping O negative blood people so get to work! I then moved to the navy blue lawn chair where I sat for 20 minutes before being addressed. Then the "vampire" said hello, poked around on my arms while mumbling something and called for a vein check. I had to ask him repeat everything he said to me. That's really a trait that you want in the person sticking a large, sharp metallic tube in your arm. Finally, the head lady who did the vein check came over and was very nice to me. She drew some dots with a blue felt-tip marker on my arm. I asked her if she thought it would work and she said the outside veins are more difficult. Great, I had been there an hour already. I really wanted this to work. The vampire came back around and hit the vein on the first try. It didn't hurt at all. I snapped some pics, ten minutes later my bag was full and I was sitting at a table sipping orange pineapple juice and eating nutter butter cookies. Thanks for the snack... and for the sticker "Be nice to me. I gave blood today."
