Boeing is having a rough time of it right now, with parts falling off its planes left, right and center. Just last week, a wheel came loose and smashed through a car, and earlier this year the door from a 737 Max aircraft broke off mid-flight. That mid-air disaster sparked an audit from the Federal Aviation Administration, which has gone far from well.
If the dishsoap is standardized in the documentation I don’t see any issue with it.
The hotel keycard, less so, since it is used to meassure how tight a fit is it will inevitably get worn, so the card needs to be durable with a predictable wear pattern, I have had hotel keycards made put of all kinds of plastic, paper even wood, they all have drasticly different thickness, wear patterns and durability.
If the documentation is too generic it looses it’s meaning.
