I hate that people give one stinking phone number connected to voicemail. I hate that you're supposed to leave a message and not know whether the person has fallen off the face of the earth or is just away from their desk. I hate that there is no receptionist/secretary to hunt that person down when you get a message late for a conference call. I hate that I missed the conference call because the only number I got was connected to voicemail. I just plain hate fucking voicemail. Only thing I hate more is endless prompts at "customer service" telephone lines - but that is an entirely different issue.
