 Chefs may also exit the competition voluntarily for any other reason; though this is not encouraged, their wishes are ultimately granted (with reasons by Ramsay explained, if applicable).Once the number of chefs drops below a certain level (usually once five or six are left) they are awarded black jackets and assembled into a single team.In the most recent seasons, black jackets are awarded by a series of rigorous individual challenges rather than dinner service, with contestants not receiving black jackets being eliminated.
