First of all, we should give ourselves a position, whether it is a tool type or a technical type. As the name implies, the tool type is to follow the procedure and follow the instructions. Then someone wants to talk. I also want to be a boss. I also want to be a manager, but I can't. I can only do what my superiors assign me. This involves a question of mentality. You are what you think of yourself. You think you are the boss. Although you are not the boss yet, you have the boss mentality. With this mentality, you will do everything wholeheartedly, because that is doing one thing for yourself, that is, doing your own thing.
Let's talk about a mentality first. We all love ourselves. Many selfish people love themselves too much. If we regard others as ourselves or a part of ourselves, will we love others as we love ourselves?
Then the problem is coming. Having said that, how to be a good waiter in a high-end club KTV? That is to do things with a big pattern of mentality, treat customers as themselves, and love them with the power of caring for themselves. Stand in the employee's position and do things with the boss's mentality.
Finally, I recommend you to go to a place called Haidilao, where there are chains in major cities to experience the quality of their waiters.
The above answers are handmade, and the price is relatively average. I hope I can help you and wish you a happy life!
