Night shift at DD

You work the night shift at local Dunkin donuts not far from where you live and everything seems to be going well, stocked goods, warm coffee, and of course donuts. You of course; had to deal with customers like the hipsters and goths who had nothing better to do at 3.am than to just sit at a coffee shop and drink coffee for like an hour. you may also notice businessmen there trying to finish up paperwork, but overall you don't think much of it. A couple of weeks ago you encountered a new type of customer. Though he was very difficult to describe, around 2. am a man walked in with a large overcoat with the collar pulled up and a black beanie on his head and had dark circles in his eyes. The entire store is empty besides the man, you, and your manager in the back whose probably sleeping.
