[RuneScape] Why is Aubury's rune shop located in a shitty corner of the Varrock ghetto and not near the city square or Grand Exchange?

Aubury is a Master Wizard who owns the only rune shop in Misthalin, and aside from Sedridor at the Wizards' Tower he is the only one east of White Wolf Mountain who has access to the Rune Essence Mine. His shop gets tons of business from adventurers and mages. 

Yet his shop is located behind the East Bank in the city's southern ghetto. Muggers regularly jump travelers outside of his shop. The city's two gangs lurk the alleys at night. 

Surely he should have relocated closer to the Grand Exchange or Varrock Square? Storefronts near the center of town must be prime real estate, surely Aubury should have bought out Zaff's shop by now? Or that useless Gypsy tent?

edit: And I am aware that the rune shop predates the Grand Exchange.

Most wizards head south and live at the Wizard's tower. 

Besides with staffs and the inane amount of runes on even the most common foes why bother buying? Especially so once you discover Runecrafting.
