The room where a shared standard is hardest to hold
A shared kitchen deteriorates faster than any other space of its size because the behaviour that damages it is invisible to the person doing it. Somebody leaves a cup, somebody else leaves a plate, and within a week the sink is full and nobody feels individually responsible. No cleaning frequency prevents that; it only determines how often the room is reset. The room is a collective action problem with a cleaning contract attached to it.
The honest position is that the room's condition through the day is a function of how the occupiers use it, and cleaning determines the baseline it returns to. Saying that plainly to the parties involved is more useful than increasing attendance, which is the response most buildings try first and which changes almost nothing about the experience at three in the afternoon. Setting the expectation honestly is cheaper and more effective than raising the frequency.
