<human>: I work for a very well known tax preparation company. I schedule appointments, take phone calls, yada yada. 

This girl calls and has an appt for late tomorrow (monday) afternoon. She wanted to see if she could make earlier. I said 'and your name is such and such?' to make sure I was moving the correct appointment and she thought I said 'and tomorrow is Monday?' so her deaf ass starts laughing at me and said 'uh yeaaah tomorrow is monday' and told her friends in the background so they could all laugh. 

Anyways, her appointment was for 4 and the only other thing that was open was at 11 the same day, so I told her and she asked if there was anything around 2, or 3. Well there wasnt. She said to go ahead and schedule and if she couldnt come she would call.  

My revenge? Normally when someone doesn't know if they can make a rescheduled appt, I offer to leave their current appointment on the books and if they can't make the earlier one, we can cancel it. I do this so they are gauranteed a spot because its peak tax business times and our appointments go like hot cakes. But since deaf ass wanted to laugh at me for her mishearing, I didn't offer to leave her second appointment available for her and canceled it. She probably won't be able to make the 11, but since I canceled the 4, that slot will also get filled and she wont be seen at all tomorrow!

Can you provide a brief rundown of the text in within 3 sentences?
