Another Chicagoan here, I'm actually the exact opposite. I'd much rather have my package sitting in the lobby of my apartment than going down to Michigan Ave, dealing with a bunch of tourists, and waiting in line to pick up, idk, a big box of paper towels because I'm too lazy to go to the grocery store?
I live in a 3 flat and most of my Amazon packages sit just outside our building in plain sight. If the UPS guy had the skeleton key that the USPS has, I'd probably feel differently.
