Why Famu says the cash box is low

Same rule as stock: your own level, or less than three days of spending left. A shortfall is only called out after three short counts within 120 days.

1. Set a low-balance level on the box, or let the three-days rule do it.
2. One short count is usually a receipt nobody entered; three within 120 days is a pattern, and only then does Famu say so.
