Keep it short and sweet

We act like we really want to have a conversation with you at your door, but unless we know you, we don’t. Basically, we just want to get the delivery over with, even if you throw out an interesting conversation starter. I will try to be as nice to you as possible, but if you complain that I’m late, or if you have a problem with your order, I won’t be so nice.
