I've graduated college with"chefs" i wouln't allow to feed my dog (even they were amazed they got through)
I've worked with un-qualified genius's (genii?)
I went on an ego trip when i qualified for a while, just cos i had done it. Ithought it was my right to be called chef.
I considered myself a chef even before my late-in -life qualifying. (big head)
Its a touchy subject. We see Celebrity "chefs" on tv. Most arnt qualified, and rely on Charisma

to blag their hyped up salaries.
Then there's joe bloggs down the road who's run a brigade for 25 years. (We all know a place like it) Not a qualification between them. and thats where you want to eat. He may not get "yes chef" yelled at him every 2 minutes. but he jolly well has it in the hat. He and everyone else knows whos chef.
I could go on and on (and often do iknow) but surely its a respect thing. Your own and that of you peers, subordinates and the public that class a good chef
