Not to mention that his use of that in response to the hot water question implies that they can't, or are afraid, to use the new capacity less it burn up. So they paid for a bunch of shiny nothing.
Still, the existence of this shower raises so many questions. Why do they need it? Its not like the shower in the house is gonna be in high demand every day, these greasy boi's ain't looking like the sort to need daily 7am on the dot showers. Are the outdoor tranchers not allowed to shower inside? Is the grid really so fragile that a 1000w or so on-demand water heater for a 5 minute shower would kill it all? Why's the floor of the shower already broken in the middle there, and who's going to slice open their foot on it first? What happens when the ground under it goes to mud and it sinks into a hellish quagmire?
