Post office on East Madison in Seattle - very slow service...
This post office has the nicest postal workers of any post office I've ever been to.
Come during non lunch hours. Breeze through the line.
If you bring your smart phone with you, you can accomplish a lot while you're waiting in the extraordinarily slow lines.
Absolutely the slowest. I would never go there if I didn't have to. Always an infuriating experience.
