Documented, sourced, and never invented. One clause at a time.
The sun-visor sticker in your car isn't generic liability boilerplate; its wording, color scheme, and dimensions are dictated to the millimeter by a specific federal safety standard. Here's what it actually says, the 1996 rule that put it there, and the myth that it doesn't really mean anything.
No federal rule requires a 'refrigerate after opening' label on ordinary condiments. The phrase's closest documented ancestor is a 1997 FDA guidance that FDA itself called nonbinding, and that gap is exactly why the words are everywhere.

Three words that turn a crime into a marketing campaign.
The warning on the back of the bag protects the company more reliably than it protects you, and that isn't an accident.
