The one thing I expect is to have a clean room when I return in the evening. I consider that part of the rate I pay. I do not care what the reason is for it not being cleaned. If there was an emergency, I am sure they have other staff that could take care of the room.

I always ask the front desk to get my room cleaned as soon as I leave in the morning. That way, it is ready if I should return early.

It is not my need to know why it was not cleaned. And any GOOD GM will want to know if this happened so it can be fixed.
