The WORST is USPS.
*ding dong* Oops, not home? The postal service leaves the tag, you get home in extreme disappointment that a)who knew you had to sign for this? b)why oh why don't I get my item today?, you have to fill out the card and just MAYBE they will bring it to you in two more days or most likely you will get a final notice sticker that it is being shipped back to England unless it is collected at a ridiculously far away branch that isn't even your postal branch during some extremely narrow window of time.
Yeah, this is never happened before....
