Genius, reading my note attached to the appointment: I see you have battery problems. I’ll just run some diagnostics… … yes, you need a new battery. We don‘t do them any more.
Me: I said I needed a new battery when I made the appointment a week ago, wouldn’t it have saved us all some bother if you’d told me then that you didn’t have them?
Genius: We’re very busy. We don’t have time to read messages.
Me: If you cut out the useless appointments, maybe you wouldn’t be as busy.
Genius: We don’t have time for that.
