In many cafes, the roaster will ask the baristas working with their coffee to serve them a shot of espresso, to make sure they're doing the coffee justice. This can be an especially interesting situation when the roaster also happens to be the barista's dom, and has a "chaotic-good" sort of alignment.
A more or less finalized sketch of a piece I've been chipping away at for a while! Love to draw up coffee gear. :F
