I hear you. Reverse Logistics can be a bear. Determining whether to return to vendor, salvage or destroy can be difficult. Vendor contracts make it doubly so.
In this case, the most profitable option might be salvage. All returned sex workers can be loaded into cargo containers. These containers can then be auctioned to various mafioso families. I hear the Russian Mafia pays top dollar.
Just a thought. Good luck with your endeavors!
