If he was really a good professional CEO and leader, he would have asked for the guys number or given his, and had his EA follow up the next day to chat in the office. This just shows how lacking in experience and measure he is, you just shouldn't act like this, especially if you're the CEO of a company that employees many people who rely on you to make sure they can put their kids through school/food on table. Arguing your supply chain costs with a component of your supply chain in the back of a car isn't constructive.
