There is a school of thought that says that there are only a relatively small number people in the world, and there only appear to be more than that because there are lots and lots of duplicates.
Whatever the reason, there certainly are a lot of eerily familiar street vendors who insist they're making such a bad deal that a specific very bad thing will happen to them, which becomes their nickname. They're all over the Disc, most cities have their own version.
If you hang around most of them for too long, you'll probably find yourself buying something you didn't know you wanted. Those who have a fixed shop do not try to force-sell to unsuspecting customers, possibly worried that an angry mob would set fire to their shop, perhaps while the owner was tied up inside for good measure.
Perhaps not unrelated to this force-selling practice, assassin guilds around the Disc offer contracts on the roaming clones.
