Seth is bored. He's finished all his jobs, the shop is clean as a whistle, all the shelves that need to be restocked are stocked, he's replied to all the emails, the tickets are all updated and he hasn't had a customer for nearly an hour. Which isn't suprising at 1am on a Wednesday.
So he leans against the counter and starts sketching. He hasn't done it for a while, months probably, but not much time passes before he is completely in the zone. He loves this.
