There is nothing to learn in the restaurant! You have to figure out what you want to do in the future, what industry you want to develop into, whether it's a waiter or a bartender. You're just a part-time job. If you want to open your own restaurant in the future, you can try to be a management! Familiar with management experience, that is to learn technology. I have heard many recent graduates say the most common sentence in society: "I want to come out and learn some skills", which is an immature performance.

What we learn in society is more about dealing with people.
