We had a customer use that one on us, together with one for specifications of a castor for a flight case (IIRC). The spec that they wanted us to quote on was for developing what was effectively a specialised desktop network switch, but it had to meet a whole host of rather dull standards. They slipped those two into the middle of the list to make sure we'd actually read and understood what they wanted. We spotted it, apparently we were the only ones of the bidders who did and declared a non-conformance with those two specs in our response.
