My school was hosting a blood drive, at first I wasn't going to because I hate needles. I get to class and my teacher offers extra credit for blood donors, still not budging I sit and do my work. Then the blood drive people came to our room pretty much pleading for people to join in on the drive. I stood up and said to my classmates I'd do it if someone joined me, no one did but since I had already stood up I said the hell with it and went with them.
After waiting and drinking water I'm finally in the room where they tested my blood, they pricked my finger twice because it was hard to draw blood from the first one. After the tests and such I'm told to lay down on the bed so I do. Then it turns out my only semi-usable vein isn't even big enough to draw from.
On the bright side I still got free food and some extra credit for trying to give.
EDIT: I still got the sticker + I should be getting a blood donor card so I can try again next time. I just wasn't hydrated enough at that moment.
tl:dr - After the tests and such it turns out my vein was too small to give. So I was pricked
twice for nothing.
