@Linkat,
He's the new Quality Control Director.
Maybe he's one of those people they send in to observe and track company slackers...you know the ones what watch him and aren't getting their own tasks done.
Perhaps he is of elsewhere and is considering purchasing the place.
Maybe a governmental sort, making sure that work conditions are up to snuff...you do have a snuff box there don't you?
Only way to find out is to ask. You don't even ask have to him. Get some poor sap in the area where he's doing his nonstop constitutional and have them ask and then get back to Mildred over in finance who will report to Wilbur in the mailroom and he will tell Clancy when he gets on the elevator to tell Ethel, who will then tell you. Problem solved.
