If my toiletry needs were large enough to hire a plumber to spend 40 hours a week in my home, I would not expect the plumber to tell me when the toilet works again. I would expect the toilet to work, period.

Clearly, I would have two toilets for redundancy (much cheaper than 40 weekly hours of plumber time). In the rare occasion when both are broken at the same time I would expect the plumber to volunteer that information. The brokenness is the exception, the workingness the default assumption.
