hello! As you said, your dissatisfaction with the boss is understandable. However, the chef has cleaned the kitchen completely and there is no mistake at all. He should not necessarily show it to the boss.

First of all, he must have the habit of cleaning up after frying vegetables. Secondly, you let the chefs in the back kitchen have a good environment. Because they are cooks, they work in the kitchen most of the time every day, and they have a clean and good environment, and they feel very comfortable.

No matter where you work, you should do your job well. You'd better not judge the leaders, which will bring you trouble. If you feel that this unit is not good, you can change it. Don't speak ill of the boss in front of others. Do you know the relationship between him and the boss? If they have a very good relationship with their boss, such as relatives or friends, wouldn't they sell you out and find themselves a job?
