Where did they find enough used condoms to make this a profitable venture? There is no way they just picked them out of the trash, they had to be at least partially presorted somehow.
I don't know exactly why, but this article makes me think of this site.
OK, but, like, for real—how do you accrue so many used condoms?
Maybe a brothel or massage parlor? Some kind of sex work business that has steady customers who use condoms.
