Rather than booming and angry, think of him as too busy, harried, overworked, driven to succeed. He is used to bossing people around and doesn't realize his effect on other people. I don't think he's angry, he's more focused on his business than anything else. Perhaps he's a bit gruff, but it's from him having a one track business mind.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
