The DL automated gate voice makes you feel like you're navigating a touchtone prompt phone system at the gate. I fail to see why the agent at the boarding door can't "invite those customers seated in zone three." In my opinion, it's a pretty direct insult to pax when there's an agent sitting at a podium looking at them while a recorded voice from above directs them to the plane. As much as I like the screens at DL gates, the voice is obnoxious -- especially at 5:20 AM.
