雞同鴨講 Chicken and Duck Talk 1988

Hui (Michael Hui) is the struggling proprietor of a Cantonese BBQ roast duck restaurant in Hong Kong. At the beginning of the film, Hui is visited by a health inspector, who finds a cockroach in his soup and other unsanitary conditions, and threatens to sue the restaurant. However, Hui's staff stop the inspector from leaving with evidence, allowing Hui to continue running the restaurant. While the restaurant is operated on ground floor, Hui lives upstairs with his wife and son. He receives a visit from his rich mother-in-law (Yan Pak), who is convinced that her daughter, Ah Kuen (Sylvia Chang), has married a good-for-nothing man. Hui faces competition when a profit-oriented businessman, Danny Poon (Lawrence Ng), opens what is to be the first of a fast food chain of fried chicken restaurants across the street from him. Danny's Chicken employs a wide range of marketing techniques that makes them instantly popular, causing Hui's business to plummet. Jealous of the employees at the rival chicken restaurant and fed up with their poor pay and working conditions, Hui's staff voice their dissatisfaction and one of the employees, Cuttlefish (Ricky Hui), leaves to work at Danny's Chicken. However, he discovers while being trained at Danny's Chicken that Poon's regimen is strict and humiliating. He is made to hand out leaflets outside the shop dressed as a chicken, much to Hui's disgust. In response to Hui's dwindling business, his nagging mother-in-law offers to pay for a renovation, but Hui is at first too proud to accept. He finds out that his son visited Danny's Chicken with his girlfriend Judy (Gloria Yip), and decides to infiltrate the rival
