Hello, I personally suggest that you don't go to a small shop to do it, because it hasn't developed much, and you may not make any progress after working for many years. On the contrary, if you do it in some big restaurants, even the minimum ability of serving, washing dishes, being a waiter and waiting for people can be improved. You have been a caterer for a long time, and your movements may be a little stiff, because you don't hold the spoon too hard when serving. The longer the time, the greater the impact on you, but if you want to change your life or cook, you should learn more from others, take a look by yourself, usually contact after work and ask the chef if he has time. After all, all walks of life are like mountains, although they all work in the kitchen, but the division of labor is different, and their experience and skills are different, so they need to practice humbly and diligently.
I hope it is useful to you, and I hope to adopt it ~
