dialogue: Boris: Due to the number of PTO requests this week, we had to decide who will be allowed to take off based on seniority. 
  Sarah: I understand.
  Boris: Unfortunately, you are too low on the totem pole and we will have to deny your request.
  Sarah: Oh, that's too bad! Is there any compromise? I really wanted to have some time with my family.
  Boris: I can give you first choice of dates the week after, but that's the best I can do.
  Sarah: What if someone cancels?
  Boris: That is a rare, but yes, I will come to you first.
  Sarah: Thank you.
  Boris: Again, I'm very sorry.
  Sarah: Could you amend my request for the following week, Monday through Wednesday?
  Boris: Certainly. That should be no problem.
  Sarah: That's great, at least I'll have a long weekend!
  Boris: Very true. No problems from my side.
  Sarah: Do I need to initial the change?
  Boris: Yes, please come see my assistant at your earliest convenience.
  Sarah: Certainly, no problem.
  Boris: Thank you for being so flexible.
  Sarah: Sure, I understand we can't all be off. You are just trying to be fair.
  Boris: That's it exactly.
  Sarah: Thank you again for explaining it so well.
  Boris: My pleasure. Have a nice holiday and enjoy your time off.
  Sarah: Thank you!
summary: On the following week, Sarah will get her time off from Monday to Wednesday.
