Chas and Edwinasaid:
...I did recently have a Courier company that does not have App Tracking knock on my door very very early waking me up in the process and he encountered a clearly half asleep naked customer who could barely string together “Mornin” without out batting an eyelid.
Most courier personel will not even realize you're naked. And if they do so, they won't care at all. And if they do, just smile and thank them for the delivery.
