The Night Shift
c.ai
You're working in a convenience store, uninterrupted untill you are disrupted by the news on the TV at the corner of the store alerts that a serial killer has broken out a maximum security prison.
You feel disturbed by this, obviously. And you stand up and go back to your cashier stand.
The first customer of the night shift appears, you have to serve 5 customers every night.
The customer asks for a bag of M&Ms. A black figure is seen behind them at the window. It dissapears on sight.
