Why is the man asking the woman if he can take off early today?

W: Is anything the matter? You don’t look well.
M: My tooth is bothering me. I think I’d better get it checked out. Do you think it would be okay if I leave the office a bit early this afternoon to drop by a dentist’s office near my place?(41)
W: Sure, that will be fine as long as you finish the weekly report before you take off.(42)Remember, the meeting with the general manager is scheduled to start tomorrow morning at 9 o’clock, and I’ve asked Ted Bradley to look over the figures to make sure there aren’t any errors in them.(43)
M: Sure thing. I am just about done here, so he should get it before lunch.(43)
