Propane tanks should be upright, right? Imagine coming home and discovering that your newly filled tank had decided to roll down the hill. A fitting broke, and LP was leaking out. We had company coming. We were able to get to the shut off valve to stop any more from leaking out, but that meant no hot water, nor cooking. Company was arriving, via motorcycle from Virginia, in a few hours. The propane company couldn't get out to help us until this morning. We offered water warmed in the microwave for a touch up bath and toasted bagels for breakfast. Thank heavens for longstanding, understanding friends.
