Cassandra was a daughter of the Trojan king Priam. She was given the gift of prophecy by Apollo, but when she cheated him, he turned this into a curse by causing her prophecies, though true, to be disbelieved.

Analyst: The model shows that customers who have a 10GB data allowance and do not use it up tend to leave us and go to competitors who offer smaller, cheaper packages. We recommend, offering them smaller packages or carrying their data over.

Manager: I am the manager here, you don't tell me what to do, look at my awesome hair!

CEO: We keep losing the customers, the analyst's models are useless!
