It's normal to steal food in the kitchen, depending on the seriousness of the plot. It can't be solved by a simple fine or expulsion. It's a palliative. My personal opinion is that "On the premise that you are the boss", stealing food belongs to gross profit. You directly link gross profit with employees, and let employees know that stealing food and wasting it are his own money, so you can take care of it. Real fried dough sticks employees drive people out early.
