What is the man trying to do?

M Hi, Sara. Is this desk available? I need to find some work space.
W Let me think. That’s Terry’s spot but I think he’s working from home today.
M That’s where Terry sits? Then I can’t work there. I just saw him in the parking lot.
W Oh, that’s right. Terry’s working from home Monday and Wednesday this week—his schedule’s always changing and I can never keep track of it. But why don’t you try over where Gordon sits? There’s an extra desk over there.
