Lol so true but for me it is UPS and Fedex that does that stuff. They never knock or ring the doorbell. They just run up toss the package on the ramp and take off. I can have a note posted on the door please knock or use doorbell if the package is expensive like the phone I ordered at the beginning of the month...Nope just dropped it and ran. USPS I can see from the front ramp of my house as my street intersects with it. They actually know my medical situation and always bring my packages to my door and knock.
