Literally the worst possible time

I am (slightly) late to work at the diagnostic center, today, and decide to drop my possessions off in the care of my fellow techs before searching out nutritive items.
Except the student store is closed.
So is the bridge cafe.
And the vending machine won't take money!

There is not a single bloody place on the entire college campus, as of now, that I can purchase a caffeinated beverage from. Not one.
Of course, it's my last week of finals. This is going to be AWESOME.
