Predatory Businesspeople in the WW was Dudley

[June Ewing]

Pippin:
Predatory businesspeople are found other places in the WW besides Knockturn Alley. Hogwarts, for example, where Neville and other gullible souls are sold fraudulent charms to protect them from Slytherin's Monster. There's a black market in equally fraudulent charms to help people pass their OWLS, and in HBP phony anti-dark wares were hawked on Diagon Alley itself.<SNIP>

At the school I would say that the kids selling this stuff were future  predatory businessmen lol. It is true about Slughorn too but he was a Slytherin and they are known to get what they want by any means nessasary. Nice guy that Slughorn but a true Slytherin lol
