Example: The story of the founder inventing the recipe in his garage is probably apocryphal, but employees repeat it anyway.

Assuage (verb) To make an unpleasant feeling less intense, or to satisfy a need.
Example: The manager's apology and refund helped assuage the customer's anger over the delayed shipment.
