Unfriendly delivery service agent

I received a call from Samuel Phoshoko regarding delivery and he asked that I have my ID and proof of address ready but because I was curious as to why proof of address was needed I asked him the reason since he was delivering to the very address he wanted proof for. He said it was company policy and I then proceeded to ask what was the purpose of the proof and he said I was wasting his time and then he said "are you going to give me these things or I will take your package back". I find this to be disappointing and unfriendly. He could have said he doesn't know why it's policy or at least directed me to someone who might know and tell me that I was wasting his time.
