Would it have mattered how excited they were? Would it have mattered if they’d told you what a pleasure it was to meet you, or how honored they were to be having a conversation with you? If they instantly went into a massive feature-and-benefit overload, a long speech that basically flung the contents of their latest brochure in your direction, would you have been happy about that?
