"Hi, I don' think I have the right department but can I speak with name."
Now the person he was looking for was in PRODUCTION who does things like ORDERING things. Now how one confuses IT Department with Production is beyond me, or he thought
"the the IT department must know every telephone number in the building, so I'll select them."
(note: the IT department is number 4 in the list, so he sat on the line long enough to decided that all the other departments weren't good enough)
