FWIW, he did do stints as (not head) chef in various types of restaurants during one of his recent UK shows (The F Word, I think), including a top-end Dim Sum place, which he appeared to find particularly difficult.

I do enjoy some of the Ramsay reality shows - as obviously staged as they are, he is fairly entertaining. We do get some of the US versions over here too, but I find the production (and I say this as nothing more than a matter of personal taste) make them almost unwatchable - the incidental music, the asides, gah!
