Is it a very small house? Or maybe some sort of storage space? Like, for people? That's exactly how YouTuber QuietGaming tried to use the booth ... and it worked fairly well. Dangerously well, even, considering how useful these storage spaces can be for members of the mafia.
Presumably, the river is already packed with corpses right up to the surface.
So, QuietGaming kept putting more and more dead people inside the booth, like a serial killer version of Doctor Who. Despite being packed beyond reason, the place held up surprisingly well, give or take the occasional corpse jitter.
It's stinkier on the inside.
Naturally, this pointless exercise soon became a challenge of finding out how many people he could fit inside. The answer: a whole shitload.
OK, mostly inside.
