hello, if this chef is a sensible person, there will be no gap between you, because what you did is not completely wrong. As far as the whole restaurant is concerned, it should be the customer first. What you say and do is all for the good of the customers, and correspondingly for the good of the whole restaurant.
you can explain this to the chef in the future. I urged you all in a false way to tell the customers, so you can fry as you like. I urged you to explain to the customers.
