Very cheap. Very nostalgic. Very shelf stable hahaha

Insanely nostalgic for long roadtrips where you'd stop at a rest stop in the middle of the night to use the bathroom and stretch, and there'd be people with hot water, styrofoam cups, and packets of tea, coffee, cocoa, and cider for free. Core memory, right there.
