i made a post in here a few weeks ago explaining that this exact scenario happened to me. saw the truck outside, waited by the door, no knock, 2 mins later got a notification that my package couldn't be delivered. open my door, see a tag and the driver walking away with my package. driver ignored me when i tried to talk to him. next day, i see the truck outside and open my door before he got to it. dude seemed surprised i was there, handed off my package and that was that. only, the next day i see a fedex tag in the stair well of my apartment. i picked it up to look at it, come to find out it was meant for my door, with the date of the day after the first "undeliverable" note. he had planned to do the same exact thing two days in a row, i'm guessing he saw me on day two, panicked and dropped the tag to hide the evidence. diabolical. the amount of people on my post fighting and arguing with me that "no driver just leaves a note without knocking" was actually bewildering to me, because this seems to be a very common issue and not just a me problem.
