I would never hug the UPS guys. In our neighborhood (1 acre lots, houses about 120 ft from the street, uphill driveways) they either leave it in the mailbox at the street (if it fits), wedge it between the mailbox and the post, or leave it in the mulch next to the mailbox (sometimes on a plant). If they are feeling really adventurous that day they drive up the driveway, remain seated, and throw the box up against the garage door, where it just falls to the concrete. Signature required? No worries, they still leave it down on the street.
FedEx (at least around here) at least does the "ding dong ditch" by ringing the doorbell and running away as fast as they can.
