Why did the boss shout at the man?

W: Hello, Jack. How did your first day at the office go?
M: It didn’t go well at all, I must say.
W: Why? What happened?
M: Well, for one thing, I was eight minutes late and the boss shouted at me. And he made me work hard all day. He wouldn’ t let me take a coffee break. He had me sit at my desk all the time J
W: Were you asked to do overtime?
M: No. We all left the office at five.
W: Well, that’ s not too bad. What do the other people at the office think of the boss?
M: They say he’ s very strict with new employees. But if you work hard and don’ t waste time, he’ s pretty easy to get along with.
