Is that for us?
(No, I'm bringing you a package for a completely different business in a completely different town).
What is it?
(Absolutely no idea, don't know, don't care).
Who is it for?
(It's for XXX).
We didn't order anything.
(Clearly you did, or someone involved in your organization did, because, look, I'm here with a package!)
That person doesn't work here.
(They do - I've met them before - they just chose to have their Zappos delivered to their workplace instead of their domicile, and I thank them, because even though it's personal chit, I still have to deliver by the 15:00 cut-off for the NDA saver).
Do I have to sign for that?
(Yes, that's why I'm waving my 'do-I-have-to-sign-it thingy' in your general direction with a sense of urgency).
