One time I was having a certified letter sent to me (from a LAWYER letting me now I was being SUED). I work hella far from home, and I'm about as far as one can be from the post office and still be in the same zip code.
Got the first slip, asked for it to be redelivered, since I couldn't just do the X. -- i.e. I had to sign for it. I asked for Friday (this was Monday) since I was taking that day off anyway. He came and went, never knocking on the door.
So I put on the slip deliver Saturday. Came and went, no knocking. If my post man was dependable, I'd have sat out there by the mail box, but sometimes he comes at 10, sometimes at 4. I tried to keep a close eye, but a girl's gotta pee sometime, ya know?
So I wrote on the slip "deliver Saturday, PLEASE knock" and that morning I put a sign asking him to please knock.
Got another slip instead.
That Monday I called the post office. They said it had been returned to sender. What? Oh wait, no, it's still here. PLEASE deliver on SATURDAY and PLEASE KNOCK. Ok sure, they can do that.
Another slip on Saturday, no knock. Now I'm really pissed, because I've spent 3 Saturdays at home watching out the damn window. And I had been assured that it would the guy would knock today.
So that following Monday I drove 50 extra miles (both ways), taking off work early, to sign for the damn thing in the post office. Of course, I was informed I could have just signed for it at home when the guy delivered the mail.
Wow, that felt good to get off my chest.
