It always amazed me that if you went to the post office to pick up your mail the charge you a box fee, but they will deliver it to your house for no charge, either paying a postal worker or around here a private carrier.
Then around here there are numerous little post offices serving very few people that employ a post master to sort mail for a half hour and not do much the rest of the day. The northern part of the county probably has maybe 2 or 3 thousand people and has at least 5 maybe six post offices
True enough but have you ever seen what happens if they try to close a post office? People scream bloody murder and write their congresspersons.
Even though the Post Office has been separate from the government and does not rely on tax dollars they still have a ton of rules and laws to deal with. They don't have the freedom to just close under performing offices like a private business could.
This is partly because of "Universal Delivery" mandating that the USPS deliver pretty much everywhere to everybody even if they live in the middle of nowhere. Also I believe there are other rules like maybe if a Post Office is the only significant building in a little town it must stay open or some such (could be wrong on that one).
Does seem odd that you get charged to come pick mail up. UPS has a similar setup. They want money for some kind of club called " UPS My Choice Premium" that will let you pick up a package at their Retail UPS Store rather than have it delivered. Of course you can pick a package up at their Customer Center anyway after enough failed delivery attempts.
