When it comes to dating people who aren't sex workers, that's more a case of, not so much asking your friends for recommendations, as your friends betting with each other on how you'll rate somebody after having dated them. A 'recommendation' isn't falsifiable, you can't see what happens and get scored on it.
Keltham can guess that's not how it works in Cheliax. How do people find the best date recommenders, is it just a matter of asking somebody else who recommended them a very good date?
