It doesn't matter if you are familiar with food and snacks and start losing money. It is inevitable that you will lose money if you start investing and attract customers at low prices. The catering industry strives to make money but makes great efforts. Even a small loss is a great exercise for you. Stick to it for a while, as long as you are cheap and good, and treat repeat customers well, you are not afraid of no customers. Once your reputation gets out, it will naturally pay off.

Other industries are also difficult to do, commercial stores have closed down and industrial investment has been slow to take effect. If it doesn't work, it will ruin everything.

Think about it. Online stores can learn to participate.
