I hate to say this.... well not really. Most people who call themselves "chef", lets say 80%, are actually fucking hacks. I have only worked with one person who is actually a capital C Chef, i.e., works the line faster, can cook anything without a recipe, creative specials off the top of his head, can control a line of "LOL I'm a pirate" retards, knows how to calculate food cost, streamlines processes, etc.
Of the other "chefs" I have worked for, I would say 60% male 40% female, the males are mostly more like kitchen managers, as in they are great on the line and good at organizing prep and keeping people in line. The females are basically diversity hires who you would never want on the line during the rush but are good at coming up with cute ideas for specials/menu items. I'm sure that there are some good actual women chefs out there, but they will never be as good as a man. To be a real leader of men (and don't kid yourself, line cooks are 90% men), you have to have the aura of "this guy is better at my job than me, and could probably kick my ass". No woman can truly lead a group of alcoholic, testosterone fueled dudes. It just doesn't work that way.
