Then I thought about it some more and decided to give the writer the benefit of the doubt - he stresses the sex-crazed aspect of the cook to paint a clearer image of the type of person, even though it doesn't really come up in the story. Starting the article with that fact planted in my head even before the first paragraph probably made a big difference to my reading of it.
[1] It's hardly unique in that; pretty much any high-stress industry with a young workforce is equally notorious for the same behavior. (entertainment jobs, military jobs, etc.)
If you follow my suggestion, then the cook will seem more than a little sex-crazed.
It's also possibly a not-too-suble nod to the comedy movie "Waiting", which featured a sex-crazed chef.
“When you’re young, you look at television and think, There’s a conspiracy. The networks have conspired to dumb us down. But when you get a little older, you realize that’s not true. The networks are in business to give people exactly what they want. That’s a far more depressing thought. Conspiracy is optimistic! You can shoot the bastards! We can have a revolution! But the networks are really in business to give people what they want. It’s the truth.”
