One of my favourite things to write is Cas being adorably confused and naive, and so this is something I wrote for a fantastic prompt in the Spn-BigPretzel Outsider POV Comment-Fic Challenge a couple of years ago.
The prompt I filled was: 'Cas attempts to order Starbucks for the first time. Dean has requested "black coffee" for himself and "some of that frothy shit" for Sam'.
How could I resist?
