There is a gas station/post office near my house, i think they need to do more of that type of service rather than stand alone post offices. If you are rural, you get a PO box, no more delivery (exceptions for disabled), sorry. Also, the gas/PO is worked by the gas station people, not actual post office employees. So there is no union or anything. I'm not sure how it works financially, but the place is always busy with people buying beer, getting gas, and mailing stuff.
