I instruct my character to walk into a late night kiosk, a toy gun in his pocket and the vaguest plan fluttering around his mind (TAKE ALL OF THE MONEY). The door that leads to the stockroom is locked. There’s only one staff member on duty and no guards whatsoever. Outside, on the street, there’s a payphone that could be used to call the police but there are no alarm buttons or security cameras.
A customer arrives and I point the fake gun at him, backing into a corner so that I can cover the cashier as well. They both raise their arms in surrender. I instruct the customer to bludgeon the cashier until he’s unconscious and then take his key. With the stockroom open, I take everything I can carry and lock the customer inside, next to the slumbering clerk. The simplest of The Masterplan’s [official site] heists executed to perfection.
