Chef! (1993)

Gareth Blackstock (Lenny Henry) is a master chef with an obsessive drive for culinary perfection, with no friends or outside interests other than his wife Janice, (Caroline Lee-Johnson) and remarkable verbal talents used primarily to creatively abuse his unfortunate staff of assistant cooks, although he is perfectly prepared to give the same treatment to waiters, management, suppliers, bankers, and, occasionally, customers.
