In a similar vein, a fun (old) article from the Washington Post about mobile lounge operators at IAD:

Alright, just passed through IAD, and it was as I suspected. A-->C runs pretty much all day; A-->D runs during peak connecting hours - splattered all through the day. You're supposed to take the C shuttle when the D shuttle isn't running.
Hope this helps.
