I've had to chase those idiots too. I don't think they do so well with rural delivery.
You're right!
The DHL "depot" in Alexandria is nothing but a large shed (I wouldnt even dignify it with the word "garage") and a small fleet of vans. It's located on a creepy backroad halfway out of town toward Alexandria International Airport where you would never want to venture after dark. One of the vans looked like it had been involved in a fatal collision and it was parked on the grass in back of the shed. I hope I never receive anything shipped via DHL again.
When I worked in New York City over 20 years ago, my employer used DHL for international deliveries. Back then, they were always referred to as "Dewey, Huey & Louie" -- I don't think much has changed since then.
