The client is one party and the users are many
In a subdivided creative or studio space, the shared kitchen, corridor, amenities and entry serve everybody but are paid for by the head lessee under a single arrangement. Studio occupants have every reason to think of the space as theirs and no standing to change the cleaning arrangement, and they will not know that unless somebody tells them. Nobody has told them, and nothing about the arrangement makes it obvious.
The result, absent any structure, is that whoever is present when the cleaner arrives makes a request. Each is small, each is reasonable, and collectively they consume time that was priced for something else. The head lessee then receives a service that has quietly reorganised itself around whoever speaks up most often, which is not what they bought. Time spent on unrequested work is time taken from something that was priced.
