Managers or janitors? I was surprised to learn that there are actually no managers in Amsterdam. Every house with windows has just a guyβI would call him a janitor. He hands the keys to the girls, and thatβs it. His only job is to be available if a girl presses the panic button, so he can help her. But thatβs all. Since the Wallen is more like a simulation of street sex work, there really isnβt a need for managers like in the clubs.
