Didn't he say that at the end of Hell's Kitchen in 2007??????
He can be lured back....depends on how much and what it is.......
Have faith!!!!!
Maybe have a Junior Hell's Kitchen (like Junior Masterchef), where children between ages of 14 and 17 are in the Kitchen and Marco teaches them, may come across better.......make it regional i.e. after various heats across the country, one representive from each area is chosen i.e. Scotland, N.Ireland, Wales, NWest, NEast, Midlands, SEast/Anglia, SWest - that would make 8 for the Kitchen. Winning person overall gets an "apprenticeship" at one of Marco's restauraunts.
That way Marco would be contributing something back into the catering industry, which is what he wants to do after all.
