Answer:
Francine: Mike, I am unhappy with your constant delay and I don't want you as an employee if you continue to act that way.
Mike: Are you threatening me?
Francine: I am not making any threats, I am stating that you are an irresponsible employee and I have already given you many chances to arrive at the correct time.
Mike: Too many chances? What chances have you never told me? In fact, I am not an irresponsible employee, you are a terrible manager, who besides embarrassing me by calling me incopetent in front of everyone, never asked me what was the reason for my delay in assessing my situation. I have done my job, regardless of the time I arrive.
Francine: You have been doing dirty and disgusting work and I am not interested in the reasons for your delay, I am only interested in you leaving my store immediately and never coming back here.
Mike: My dear, kicking me out of the store is a favor you do me. I don't want to work with someone so rotten and rude.
Explanation:
As you can see above, the dialogue was written with the two characters being aggressive. Both could have taken another approach to deal with Mike's delay problem.
This other approach would be to establish a private conversation between Mike and Francine, where Francine would ask the reason for the delay and calmly explain to Mike the harm that this delay is providing to the store, in addition to looking together with Mike for ways to minimize this problem. Mike, for his part, should listen to Francine calmly and ask for advice to resolve his delays.
