Seen this real-life: management ask for some unannounced change on prices. Everyone in IT tells them "this is gonna backfire fast". No way to budge them on it so we apply. A couple hours later support and sales are getting hammered by unhappy clients so we get to rollback as fast as possible. The official excuse? "That's an error from IT". Nope, the code worked perfectly and did what was asked of it.
