He expect perfection when he wants something, like the drink! But can't be bothered to provide the same with his products? And God forbid if someone dares to criticize "his inventions"! Comes to works and can't stop blabbering about stuff even when the other guy says he isn't interested! But when someone else does it to him, it's jarring!
If he was consistent, I would mind,but he's just a self-absorbed hypocrite!
And if he didn't have knowledge(other people knowledge)from his previous life, he would probably live from his family inheritance or some kind of trust-fund
