Yeah, its in the culture so everyone who gets into it ends up smoking cause everyone else already is. Strip clubs and such come into play too, after work. Yeah, they have to be STJ, they all act like it, and if they don't they are crazy in some other sort of way. The only normal chef I met was one of my teachers, I imagine he made it through by just being really calm and stable.
I was treated badly but more as per the fact that all the students were worthless loser drunk types who naturally would bully others to gain what little self-confidence they could. They all acted like convicts, really.
