Excuse me. Do you work here?

Library Patron stories:
(Me at the reference desk at 3:30pm)
Patron: Can I put my name down for the study room at 4pm.
Me: No, I'm sorry it's first come first serve. So you will have to come back at 4pm.
P: But I asked the girl and she said she will be done at 4pm.
M: You'll have to come back then to get it. You can't reserve it in advanced.
P: But she said I could.
M: Who did?
P: The girl in the room.
M: She doesn't work here. I do, and I'm telling you you can't.
P: Oh ok.
