Without a notebook, he wrote an entire book while working.
The author was adamant about finishing his book while working as a cashier, and he was unaffected by the regulations. Since he couldn’t use paper or notebooks, he made the creative decision to cut waste. He took out all the receipts he could find and, wherever he could, jotted down passages from his book. Before he could make the scenario into a reality, he collected enough receipts to almost write a novel.
He truly was able to utilise every minute of his shifts in order to gain money. The book was eventually finished, released, and even sold.
