I hear ya on the sleep thing... I'm sick as a 1000HP Supra right now and despite needing sleep desperately all of my symptoms have prevented it for days...
That and I'm also an insomniac.
You can get a plastic one at Harbor Freight or many hardware stores for a buck or two... So I'm going to assume that they A) didn't think on it B) aren't able to get to the car or C) are just being lazy.
