Via the appropriately titled Hella Proper:

Cookies Sold by String Dangling From San Francisco Apartment Window

‘San Francisco entrepreneurs Eve, Kathleen and Clem of Fat Cookies deliver their oven fresh product (baked in their second story apartment) to their customers below by way of an ingenious bag and string hoist. Sharp-eyed readers may recognize this style of product delivery from such drug crime dramas as “The Wire.” To get your fix next time you’re in Dolores Park, follow Fat Cookies on twitter.’

gotta love SF.
