You have to choose between dying an having something to eat.
This is the case in some parts of Africa in particular. I was recently reading that in South Africa, women prostitute themselves for a meal. You can call that a job if you like, but the reality is that if they are to eat, the only thing on offer is to give a man a blow-job. She doesn't know whether the man in question is going to kill her just for the fun of it, or beat her, but she hopes to be able to eat her next meal.
