Man: Here's my invoice for the extras. Dilbert: The invoice we already paid covered everything in the contract. Man: That only covered the costs I quoted with intentional clarity. There are other costs that I might have mentioned in the long and rambling explanation that was intentionally ambiguous. Dilbert: "Might have??" I'm sure you did not. Man: Sounds like your word against mine. Dilbert: And even if you did mention it, you just said it was intentionally ambiguous!!! Man: I don't think you want to tell your boss you're a bad listener. Boss: I thought we already paid this vendor. Dilbert: Did you forget all the extras I told you about?
