I always think it's funny when grumpy people talk about abolishing the postal service. I can't imagine what it would be like, with only a couple private carriers, and Jeff Bezos' in house shippers, airborne UAVs, and whatever other crazy stuff he wants to do... monopolizing all shipping.
I just noticed a little $3.20 FedEx fee attached to a shipment the other day. I call in and ask what it's for... They tell me that even though the customer charged the shipment to his account... they auto-billed me the $3.20, because: "we were the ones that arranged for the shipment". So basically, they got their delivery fee, then they charged us for essentially, filling out the web form. UPS charges us the $8 fee per pickup if we use them, because... even though we are in a massive urban area where their trucks are going up and down the streets all day, they still technically consider it a "residential area". No amount of coaxing has gotten them to stop charging this. And it's not like either one has improved their service over the years... Their guys just keep getting more lazy and less intelligent, as the years go by.
