Just how stupid do you have to be, not to realise that a floor sagging (which you just removed supporting walls from beneath) is a Serious Problem?

I suppose this is another triumph of greed over ethics - don't want to miss any paying guests while you close for inspection.

This seems to have an element of scapegoating - going after the engineer dude. So if you invent something, you're responsible for ensuring every use of that is properly maintained throughout its lifespan?
