I believe 100% in donating blood. During covid the Red Cross was begging for donors due to the nations low supply and even giving Amazon gift cards. One morning I was driving past the local red cross center and decided to donate. I've donated to the red cross before via blood mobile at my hometown a few miles away. The center had just opened and my car was the only one in the parking lot. I entered the building to what seemed like a ghost town. I was finally met by some guy after a couple of minutes. I said I'd like to donate blood, he asked if I had an appointment, I said no, I didnt. He said I need to call in to make an appointment for donations. I said, "you dont take walk-ins"? He said appointments only. I said I'm the only person in the building I cant believe you cant squeeze me in. He said appointments only. I said, you must not be short on blood if your turning away people willing to donate, then left.
