The failure mode is ordinary. The phone rings during flu season and the week a new tenant moves in, when a five-night contract cannot skip a floor, nobody answers, and the lobby is still dirty when the first employee badges in.
Uma answers and writes square feet, floors, and that the crew starts after 7 p.m. before talking about a clock time. The Cleaner minutes turns those counts into cleaner-minutes so the company sees a size, not a vague "can you come look."
Then one company is offered the note. A local night crew does the floors. Uma does not hold a key until the company claims the job. If the window cannot be met, the caller hears the next real opening, not a promise that keeps the board pretty.
The note is the product. A callback that skips square feet, floors, and that the crew starts after 7 p.m. creates the second angry call.
