I tried and found a cheat code! It turns out that if you pass out during the draw and then pass out again while recovering they’ll call and pay for a cab to take you home! They did imply that I shouldn’t come back for a while though…

On a more serious note I had donated blood twice before that with less dramatic results. I like helping people and they give me free snacks afterward. I’d been going every three months because I was in university and had a lot of time for such things. I seem to feel quite tired for the rest of the day following a donation, which I found nice and relaxing. Needle anxiety (and my weak-ass hemoglobin level) aside, it was a positive experience and I’d recommend it!
