Wally puts half a pot of coffee in his cup. Wait 'til that gets percolating in him. First time I have ever seen him congratulate someone. Random guy should get the camera footage from the security guys and frame it....
Couple of things
1) If this guy knew enough about Wally to block the door AND the air vent then 2) why would he bother to even seek Wally out for an answer to anything unless 3) he is equally incompetent and needed someone to blame
