John has a secret passion for coffee...more on that later.
The Artistic Type
John jumped over the counter fairly adroitly, Sherlock noted, but noticed that it was his left arm that he favored. So the right one was shot, he thought. He's been unable to recall which it had been during their formal introduction.
He could hear Mike's bleary voice from the back. "John, what are you doing here? 'S not your shift…"
"You know I've got a thing for coffee," responded the sandy-haired barista teasingly, emerging from the back, clumsily tying his apron as he walked. He looked at Sherlock and grinned.
"Coffee," he said, "is a bit of an art."
Prompt was #94: sand (did I fudge it because I said "sandy"?)
