The post office is a royal pain in the ass. Takes too long to get through a line and the people working are, from my personal experiences in L.A. and New York, often not particularly kind. But, I gotta give them props for a great idea: R2-D2 mail collection boxes. It's a whole campaign, which will include Star Wars stamps, that is being rolled out over the next few months.
While the Star Wars prequels generally sucked, those first three will always hold a dear place in my heart. Of course, in typical USPS fashion, no word on how to actually find the R2-D2 boxes. Some things never change.
