The cost of a missed ATM service call is specific. The lobby machine stays dark through the friday rush.
The caller had the terminal id, the error, and how many cassettes are empty. A voicemail that says "call me back" drops all of it. They do not reconstruct the note for the company that failed to answer.
Friday afternoons and the day before a holiday, when cassettes run out together makes the miss louder, because the next company that picks up takes the window. Grit writes the terminal id, the error, and how many cassettes are empty while the caller is still on the line, then a local company calls back with a real time.
The Cassette note count is the planning total, notes to stage. It does not bill anyone. It keeps the callback from starting at zero.
