In the culinary world, where you work in a kitchen everyone is called Chef. Yet, everyone in the kitchen knows whose boss.
In some culinary worlds, perhaps.
Where I worked, there was one individual referred to as "chef" by everyone who worked in the kitchen. Among the more printable titles used for other kitchen workers for one another were "dirtbag" or "cabron."
On the other hand, it is true that just about anyone working in the kitchen might be addressed as "chef" by front of the house staff who were looking for favors. But then, they were a) front of the house staff b) looking for favors and c) professional flatterers.
