The Chief Steward had the job of overseeing the stewards. He is mostly seen in the First Class Dining Saloon.
On the first day of Titanic's maiden voyage, he sees Paolo Sandrini, the only Italian steward, wink to Lady Georgiana Grex.. He summons the steward for a warning: flirting with rich passengers like the Mantons is very offensive. 
The Chief Steward escapes the sinking Titanic by dressing up like a woman and boarding one of the last lifeboats. Unfortunately for him, that boat was commanded by Fifth Officer Lowe, who emptied the boat in a pontoon to go back for survivors. Lowe removed his shawl and exposed him to everyone in the pontoon, and the Chief Steward quickly moved into another boat.
