I can't find info about it now, but I'm pretty sure in the 60s in South Africa, if you regularly donated blood you got to be bumped up the system for various ops and waiting lists, and if you had to stay in hospital you were offered a better bed/room. Sure I remember my relatives talking about that in some long ago conversation.
