The whole kitchen hierarchy has changed, everyone in the kitchen is titled "chef something" now-in-days. Add to this the media attention from FoodTV, everyone wants to be called chef regardless of background experience or position.
I have 3 years under me with 2 years of schooling, I've been offered the chef position where I'm working twice and at other sites, I can jump into anyone else's jobs in the kitchen and do it with a fair degree of efficiency regardless of how often I've done it before but I will never refer to myself as chef. I personally don't think of myself as chef, nor do I truly want it anyways but regardless, I'm not a chef.
Then there are these punks out of school, wearing an assortment of facial jewellery, arm hairs longer then the hair off the top of my head, wearing baseball caps, doing half the hours I am, touting around with Chef [insert idiot's name] engraved on their jackets. I get a little giggle out of it and put money into the pool "how long with this newbie last"...
