So the delivery system is a team of latina women, sometimes a man driving, in minivans driving around for the deliveries, making efficient circles. The women delivering the papers will run or speed walk to a building, get in an elevator, punch buttons of the floors they deliver

And they will throw the newspapers left or right at each floor before the door closes, in the direction of the apartment. Presumably cos stepping out will be add to the time and they want to be out of this building to meet the minivan as it circles back, to go to the next bldg.
