No, you do what normal delivery people do and leave it at the security desk. Or with the guy hanging around outside the front whose job it is to wave his arms at taxis and move the beggars on. Or the drone landing bay the building installed on the second floor terrace balcony because the tenants wanted it. Or maybe they actually won't be leaving packages in random locations, and instead require you to actually be there to acknowledge the delivery. Maybe there are solutions to problems.
I think the first place to get a system like this will be Tokyo though. The culture loves robots, and I imagine some depots could service 10 million people in that 10 mile service radius. Not only would you deliver your own product, but you would steal almost all the existing document and small item delivery market.
