It's a machine that used to be well oiled but management's been deferring maintenance for decades, the oil's gross, it's leaking everywhere and overheating, it's barely hanging on, and the manufacturer's long been out of business.
But the people writing the instruction manuals every year are convinced they are the only ones able to understand the original manufacturer’s intent. Thus all the constant changes they are making to the instructions are perfectly valid and everyone should follow those. Also bear traps.
