1. Cultivate employees' awareness of serving the people, and don't show it in words or slogans. Use actions to explain.

2. Serve customers as relatives.

3. Always remember that the customer is God, but don't let God think that you don't deserve the money he gives you, because every God is a god of wealth.

4. Clean and sanitary like McDonald's.

The most important thing is that the boss should have the awareness of training. Don't just make money.
