The failure mode is ordinary. The phone rings during Saturday birthdays from spring through early fall, when every 15-by-15 wants the same noon window, nobody answers, and the party starts with the castle still on the truck.
Umber answers and writes the unit size, the blower, and whether the lawn is flat and dry before talking about a clock time. The Setup minutes turns those counts into minutes of setup so the company sees a size, not a vague "can you come look."
Then one company is offered the note. A local crew sets and strikes the unit. Umber does not supervise the party. 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 the unit size, the blower, and whether the lawn is flat and dry creates the second angry call.
