Zainu's Motorcycle Repair ServiceZainu, a student in the automotive engineering program in Semarang, had always enjoyed fixing bikes. Since junior high, hed been helping his uncle at his small garage. One day, during his final year, he started thinking seriously, What if I open my own repair service?"He only repaired bikes for friends in the neighbourhood at first, such as changing oil, fixing brakes, and cleaning engines. He didn't charge much, just enough to cover parts and buy better tools. On the weekends, he worked from a small space behind his house and sometimes stayed up late to finish a job.He gave his service a name "Zainu Bike Fix" and posted some photos of his work on social media. Surprisingly, people began sharing his posts. More students from his school started bringing their bikes to him.It wasn't always smooth. One time, a customer complained that Zainu took too long to fix a bike. Zainu apologized and offered a small discount. That experience taught him the importance of communication and time management.Over time, he learned how to handle not just machines, but people too. He began recording his income and expenses. He also saved enough money to buy a new toolbox. By the end of the semester, his teacher even used Zainu's story as an example in class. "Zainu didn't wait for a job. He created his own," the teacher said.Now Zainu is planning to rent a small garage and hire one of his friends as an assistant. He says, "This is jus tthe beginning."
What lesson did Zainu learn from a customer complaint?
