What a 341 number signals to a caller

A 341 number is the East Bay's second code, and 510 has marked Oakland since 1991, deeply enough that "the 510" functions as an identity the way "the Town" does. Callers describe Oakland business style as direct with a low tolerance for polish that outruns substance, a habit refined by proximity to San Francisco's pitch culture and a deliberate distance from it. An outside caller does better stating terms plainly than performing enthusiasm.
