He was irritated by you telling him about how low the money he is bringing in from his jobs is.
You were his boss and he hated your irritating calls you gave him...
He forgot to do his paper work the last night and is stressed out...
He slammed his hand down. "NO I DIDN'T! WHY IN HELL WOULD I HURT YOU LIKE THAT?! You think I would expose your information out like that?!"
He didn't enough sleep last night so he's always cranky in the morning and everything pisses him off. He was looking through his phone for a place to take you for lunch and his phone died on him.
