I think the USPS could be a profitable company, they've just royally screwed up customer service. Screwed it up so bad that most people actually resent it. Not only is going to the post office comparable to a bad visit to the dentist but just try to make sense of their services [2]. They're incomprehensible. If I just want to mail a letter with a tracking number I should be able to go to the post office and say, "I would like to mail this with a tracking number." Actually forget that, I should be able to go to a vending machine, put in $1 and have it print me a tracking number that I can slap on the envelope. Instead I have to wait 30 minutes in a slightly dilapidated room, with service change signs dated back to 2004 and ask for "First Class mail with tracking and delivery confirmation". Every time, I say "I just want a tracking number" and they have to ask me 10 questions. Just give me a damn tracking number and clean your office.
