For example, take you and the chef. If the chef says it is better to steam vegetables in a thick bowl, you can ask him calmly: Can you steam vegetables in a basin? He will definitely answer you calmly, yes orno. If you tell him so and ask him by asking the chef for advice, he will definitely answer you with a happy tone. If you ask him in the tone you mentioned above, he will definitely think that you are arguing with him. That's why there is unhappiness between you.
No matter working in any unit, the relationship between colleagues, employees and bosses should be tacit and coordinated in order to do a good job as a whole. If the whole is good, it is also good for individuals. This is the so-called "one glory and one loss."
I still wish your restaurant a prosperous business and rich financial resources!
