I met someone at the airport near Balota who caught me bandaging and was friendly enough to provide me with a blood transfusion. I noticed that my screen was fairly desaturated and decided, what the hell. He checked my blood and his blood and assured me I was AB- (the universal recipient). When the transfusion was over he said "Bye Sucker" and ran off while I died. That was probably the most expensive backstab I have ever seen.
