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.

Customer:  There’s something wrong with my watch. It’s running slow.
Woman:  Oh, a Texor. It’s a common problem with the older Texor watches. The latest ones are much better!
Customer:  That’s no help to me.
Woman:  No, I suppose not. Anyway, it’s not easy to get them fixed, either. Not many people are up to it.
Customer:  Right. So ...?
Woman:  And the problem is that by the time you’ve got it to pieces and put in the new parts and reassembled it, you might as well have replaced it. It’s always the same, and it’s just as likely to go wrong again in a couple of months.
