Jack began walking towards the manager step by step, as he questioned, "I thought that I called you and asked you to come here. And true you came, but you actually completely ignored the fact that I had called you here. What do you have to say about that?"
The manager had already began sweating, as he continued retreating two steps with every single step that Jack took forward. And when he heard Jack's question, he remembered about the time that he had been called by his boss.
At that time, he was actually talking to Wilson. And, he had thought that, even if his boss wanted to sack him, he would not be able to do so, if he himself possessed the backing of a member of the Lincoln family.
So, at that time, he didn't even bother to listen to what his boss was actually saying. All that he heard at that moment was that, he was supposed to meet his boss somewhere, which he didn't even remember.
