Today in The Nutshell (which is what I shall be calling the store from now on), I was carrying the table top that I put up to organize shipments and subscriptions, and as I came around the corner, a guy who works across the hall, whom I've never heard make a noise in the seven years I've worked here, made a sharp barking sound.
One of his coworkers stopped in later to ask me a question, and I mentioned the run-in.
Me: "It's the first noise in seven years. I used to take it personally when he never said 'hello' but then I figured he must have some sort of cognitive or speech issue."
Guy From Across The Hall: "No. He's just a huge asshole. Everything he says is terrible. He was my roommate for a few years, and he kept getting fired from jobs for being a prick. When I got him this job, I told him that if he said anything to get fired, I would kick him out of the house. So he doesn't say anything while he's within 100 yards of the building unless he's answering a direct question from our boss. And he won't go near the counter so that none of the customers can talk to him. He has his own place now but I think he discovered that life for him is a lot easier when he just shuts the fuck up."
I'd like to recommend this to several people.
