It's a great mini-dungeon for modern surreal horror. I stuck it into a delta green campaign, and it was probably my most successful session yet.
I added a bored hipster sales assistant at the end and one of my players bought a camera. He also made friends with the attendant somehow, so chances are we'll be returning ¯\_(ツ)_/¯
