I Work as a Concierge at the Killer Hotel

At that time, I had just lost my job and was so poor that I was struggling with the few cents in my wallet. Just then, I saw a job advertisement for a hotel concierge with the slogan "high salary, simple accommodation, and food included"! I felt happy, the concierge, didn't he just stand at the door and say hello? It's so simple! Who would have known that on the first day I checked in, I discovered that every guest in this ghost place was scarier than the last! Some were wearing black clothes with daggers hanging on their waists, some were wearing sunglasses and lowered their hats as they entered, and one was carrying a black bag with several bullet casings falling out of it. Wait, wait, who else is wearing a hockey mask with bloodstains on his body?
