Donating blood is free! Something about jamming an 18 gauge needle into a vein in my arm kinda irks me. You see how fast that vial fills up at the docs office?! You won't have a vial, so your gonna have to pin the vein free-air, so I imagine your gonna do this outside like naked right... so blood doesn't get all over your cloths.
Imagine if your neighbors see you.
" Yeah that's just my next door neighbor draining his blood. IDK why he's naked but hey that's his business not mine."
Lol really though I do understand the problem here, to me its a moral issue. A blood drive works on donations a lot of times. Even if the money isn't donated its still being spent by someone. You willingly donating dirty blood is almost like stealing.
