On a train, you overhear a woman phoning her office. Why has she phoned?

Woman:  Jenny, hi, it’s me. I’m on the train and it’s stuck somewhere just outside the station -- signalling problems or something ...Yes, I know, sorry, but there’s nothing I can do about it. Anyway, listen, could you check my diary and see when I’m supposed to be with those marketing people ... it’s on my desk  ...... Oh, isn’t it? Oh, that’s strange. And it’s not in the drawer? I wonder ... Oh, I know, I must have left it in Jimmie’s office after yesterday’s meeting. You couldn’t get it and then ring me back, could you? Sorry to be a nuisance.
