UPS always dumps stuff out on your doorstep and drives away. "Adult signature required" or not they just leave it. Asshats left a package containing 4 full-auto HK MP5 submachine guns sitting outside the front door of a police distributor my friend used to work for. They didn't get there by 5:00 pm on Friday when they closed and Monday morning the boss came in to open up and found them sitting there. Luckily nobody stole them or there would have been holy hell to pay with the BATF. As it was UPS got an earful for that one. The boss practically had a heart attack.
