When I'm cooking at the pub (I occasionally do so at my local) I always think about DJK... Last night i was thinking about his choice of workwear and job.
Although it's not the norm for 'dish pigs' as is the industry term, or 'dishies', to wear chefs get up, it's not completely out there either, I've seen it before. Especially that he's chosen black for his top, black tops for dishes is the norm, because you're dealing with a lot of mess. Chefs pants (depending on style) can be quite comfy, so I can understand that too. Also bearing in mind that he's a young man living on the north shore and eating out and having coffee etc in his work clothes, so no doubt he wanted to present himself well to any prospective 'partners' or 'hook ups'. It's no different to the tradition in some workplaces where on Fridays you wear a slightly less corporate and slightly 'hotter' top under your suit to be ready for Friday arvo drinks in the city, because you just don't know where your night might take you

you want to look good in your work clothes!
On him telling people that he was a chefs assistant, well it's true, technically a dishie is an assistant to the chefs. They pick up and clean up after the chefs and sometimes do other jobs for them. This could be grabbing supplies from stores or actually helping with prep and even helping with plating for large functions.
It's also a good foot in the door for someone who wants an apprenticeship but has been unsuccessful finding one. You get in there, work hard, show initiative and when an opening comes up, you're a shoe in for the job. I've seen it before.
The 'chefs kit' that he apparently told people that he had in his satchel May or may not have actually been there. That's an assumption we shouldn't make IMO.
Though if he did in fact have one, it could have been in preparation for him getting an apprenticeship. Chefs are really protective of their knives an most won't even allow dishies to wash them up, they'll do it themselves. Knives can be exceedingly expensive and they really are their tools of the trade. So to someone desperately wanting to become a chef, I can see how owning a set of knives could make them feel that much closer to achieving their goal.
All MOO of course, make of it what you will

just some 'food for thought'.
I'll also add that I'm not saying that I believe DJK DID think this way, just that it's a possibility that someone in his situation could think this way.
