The thing about the USPS is that despite all of the reagan-esque bullshit that's been done to it, it's still a far more human entity than any of the commercial parcel services. For instance, my office has two different addresses, and to try and figure out which one was actually recognized as the official address of my building I mailed letters to both of them from the local post office, giving myself as the return address. the carrier put them in my box with a rubber band around them and a note telling me not to do that and also what the correct address was.
this is why I cannot stop thinking about the idea of sending a slice of pizza to somebody with media mail, because the post office is authorized to open any media mail they think might not be media and return it to sender, and there's a good chance I would get it back with a note inside that just says "Go fuck yourself dude"
Don;t do that
