I've yet to find work-study coverage for Wednesday mornings, which has thus far been the most difficult shift to schedule during the week. It's funny -- you have morning people and you have evening people, you have weekend people and you have the Monday people, but I have yet to see someone who is a genuine Wednesday Person. Sure, it's "Hump Day", but that's just an attempt to sugar-coat a day which has no redeeming values whatsoever. Those of us in the 9-to-5 workforce are obliged to show up on Wednesdays like any other day, but those who do shift work have no such incentive to be here.
Fortunately this desk can be manned by one individual, although visiting researchers can make it so that that solitary desk worker doesn't get a moment to sit down and catch his breath or even blog (Dewey forbid!). It does make the day go by in a blink of the eye, however. All you have to do is stay hydrated, keep smiling, and blog when no one's asking for their stuff.
