This bitch is getting all hostile on you. Screaming that your an idiot and She's gonna "have your job!". You do the natural thing. You slug her in the chin so hard you knock her clean out. Laying in a pile covered in steaming hot coffee. You roll your chair back into your office and lay low until it's time to clock out and go home. You never see her again. When the boss don't get his coffee in a timely manner he fires her. No excuses.
