Ah, offloading the physical movement of papers between the offices onto the general populace... why don't they just mail each other directly, isn't the part of their job is to communicate with other offices? Lolnope.

Sometimes it becomes truly ridiculous: I once had to apply for some thing, and was told I need to grab and provide them some certificate from a different government service to prove that I'm actually eligible. Okay, I do that, and then they spend two weeks verifying the certificate by physically mailing and inquiring info about me from that other service and waiting for them to respond (also by physical mail).
