South Africa-Zimbabwe: Sex for soap, salt and sugar
The border between South Africa and Zimbabwe is more than an international boundary; it also determines the method of payment for sex workers, because on one side cash is taken, while on the other, goods are bartered.
The South African frontier town of Musina is a regional trucking hub that has long been a haunt of sex workers, who use the boredom of truck drivers waiting for their cargo to be cleared by customs as a window of opportunity.
