Problem: The Thimble Corporation recently distributed rebate coupons for one of its products  Some of the coupons bore an expiration date that was too early  This created an unfair situation in which some customers believed, incorrectly, that the rebate offer had already expired
Principle: Anyone who creates an unfair situation has an obligation to rectify any unfair result of that situation
Because it cannot identify all of the customers who were adversely affected by the incorrect expiration date, the Thimble Corporation should deny the rebate to all of the customers who applied for it.
