Issue One: CJ described it as their "goofy happiness", which (I think) was a euphemism for "We're kinda-already-drunk-if-not-completely-hammered." For any respectable chef this should be a non-issue.
Issue Two: Wardrobe. As far as the whole attire/gender complaint, all chefs--man, woman, or Hung's monkey--deserve to be protected in the kitchen. The producers should have made their clogs available. Didn't they learn anything from Hubert Keller telling Cynthia to leave the kitchen because her shoes weren't safe in Season One? As far as shirts, Tre didn't seem to be using his--someone could have borrowed it. They also apparently had aprons available (as well as bad hats).
Issue Three: And I quote, "Everything is F*&@d." In the kitchen, when things are f'ed, you have about five seconds to be "demoralized" before you need to get over it (and yourself). I've found myself literally knee deep in, well, what you don't want to be knee-deep in. I've cooked in a kitchen with a broken fan and vomited every night from smoke inhalation. I've climbed on roof mid-dinner service to repair (or further break) the aforementioned fan. Things get f'ed on a daily basis. A chef kind of has to like that aspect of the job (just a little bit) because at the end of the night, you will know you were victorious. I guess Sara didn't read "Kitchen Confidential". But I can totally understand having a bad day--I had my share--but CJ's pep rally would have been all I needed.
