They're the ones pouring it, and the ones that will have to listen to me bitch if it isn't what I want. At this point, it doesn't really matter since I won't have power for a while. I'd just have to heat it while waiting for electricity and that means baby sitting a generator every day, (and on a suitcase that likely means changing the oil daily, along with topping off the tank), and pouring through propane for no reason. Although I think if I pre-measured the oil out, I could likely change it in less than five minutes.
