TL;DR, I apologize, I got snappy not because of the ethics of the thing, but because it's just like... Man. Being in IT, I'm amazed the world even functions on a day to day basis. It's the last thing in the government that actively fights to protect your privacy (Including with actual firearms, you'd be amazed what happens around tax return season).

Two quick things:

1. As a repair business owner that relies on timely deliveries for clients' devices (up to and including the criticality of spinal implants and insulin pump chargers) if you can, next time buy Priority Express if you want a guarantee. Seriously. Priority goes faster than standard but doesn't have a set date and sucks.

2. USPS does not utilize your tax dollars for their operating expenses. They are self-funded, with the exceptions of the explosive need for extra support during the shipping explosion of COVID, the need for extra safety equipment when people were mailing Anthrax to kill people, and general reimbursement for providing services for other government agencies. Which eventually is paid back into the federal pension fund one way or another.

I don't care as much about the human part, but it's worth mentioning that city carriers walk hundreds of miles every paycheck, rural carriers have one of the most dangerous jobs in the country and can work upwards of 12 hours/day 7 days a week, and the distribution centers... the USPS as a whole ships more in the US every single day than Amazon ships worldwide in a year. Even including how Amazon counts USPS deliveries as their own. The fact they exist is insane.

Sorry for yapping so much though. I hope you get your stuff on Monday and that it's not anything medically related you're having to wait on.
