We are to believe that Marlon is actually a good chef. In which case, if he stayed behind the scenes at the B&B (from a client point of view, not a telly viewer point of view!) I think that he would be an asset. The B&B could do with a bit of vigour injecting into it, again we are led to believe, and he could give them an impressive menu, which would certainly help.
Good call Nemisis!
