Non-Existent? I respectfully disagree with this. There is no question that 3 can do it better than 2, however we've been mandated to work differently on this aircraft. During the course of service while in Y/C, it's not uncommon to return to the forward galley a dozen times to replenish beverages, coffee tea, water, etc. In doing so, I survey the J Cabin and observe whether drinks are in need of replenishment, dishware/glasses need to be picked up, etc. There is no question that the SD is much less idle on this aircraft than before, and one has to work diligently.
