I know its a joke, here though single storey is better because of tornadoes. Sometimes they can skip over a single storey house where if it was a two storey job it would just lift the entire (timber framed) lot off the foundations. The wifes boss was hit the year before covid; the edge of the tornado hit the house of the bloke over the road so that it took the brunt and it more or less skipped over H's house, still causing a couple of hundred $ worth of work.......prices all seem to go up when there has been a tornado.
I though the combination of the toilet block being used Hurricane Shelter at my last company's Dallas Warehouse was pure genius.
Should the wind get up and you have to retreat there to survive, you wouldn't have to go far to avoid messy floors when you started shitting yourself
