You've got to wonder what it's like to work in a office where everyone is refered to as 3E, or 4B or 6C. "Did you hear? 9F is having an affair with 5G's son-in-law, 9L". "9L? Isn't he the cute mail-boy in sector 11H?". "No, you're thinking of 55K, 9L is the plumber who once dropped his pants in office 3X on floor 5 of building 78P".

But back to the image - clearly blondy is 3E. And the supervisor. Nothing else here...
