Things are slow here right now, as the sun slips down past the city's horizon. That's why Shin took this shift, after all. Right now he's currently using the time to clean out one of the two machines' filters from the day's gunk; he doesn't actually care all that much about the coffee but he does like keeping his job and keeping busy at other things balances the books for avoiding customers, possibly.

At least it has so far.

His coworker left their overlapping hour fifteen minutes so he's alone here. Shin deliberately doesn't think about having to walk through a sketchy area in the dark, because he has to do it near every weekday, and after a certain point stress itself wears thin.

So when the door rings as someone enters, he's caught just a little off guard. There's some clunking noises as he puts various components down and yells 'Be right with you!' And then a hiss, and flattened ears, as he hits hot metal.
