This appears to be what first-timer director-co-screenwriter (with Olivier Lorelle for the adaption) Sylvain Desclous wanted to show in his debut film Vendeur (Who's Your Daddy?) (我阿巴是誰?), starring Gilbert Melki as Serge Ponsini top salesman in a luxury kitchen euipment company, Pio Marmaï as his chef turned salesman son Gérald Ponsini, Clémentine Poidatz as Gerald's devoted cohabitee ,Karole, Sara Giraudeau as Serge's regular call girl who is doing a master in marketing degree. But this is not all, the debutant director appears also to want to show that ultimately, whether one wants to remain a salesman all his life and have that kind of lifelstyle is ultimately also an existential question of what kind of person one really wants to "be" and of what one considers will give real meaning to one's life.
The film starts with a team of salesman in action. Every morning, they would gather together in a room, with a pep talk expert, who would motivate them to fulfil their daily sale quotas by collectively shouting some notionally meaningless sound the sole meaning of which is to show their common solarity and determination to start off the day by doing their utmost to push sales. Then we see Gérald meeting Serge for a breakfast in which the son tells his father that he needs a job to help him get money so that he can renovate his small restaurant and that he wanted to become a "salesman", like his dad. Serge was initially reluctant but later relented and introduced him to join his compnay. Initially, he did poorly but at key moments, Serge telephoned him through their mobiles to give him tips on what to do and in a very short time, he showed that he could do as well as his father but at a quarter of his father's regular pay, ex commission.
When the film ends, we see Serge being laid off but found another job where he could use his salesmanship skill and Gérald's girl friend dumping him when she discovered him flirting with one of his lady customers. When the film ends, we see Serge reading with obvious satisfaction a newspaper article about his son resuming his restaurant business in a big way. His son had apparently learned a lesson.
It's a simple story but Desclous Sylvain did not develop Serge's relation with Chloé when their relationship is portrayed as something more than the usual customer-prostitute relation. Perhaps merely wishes to her to say something he wanted to day, viz. that the life of a salesman is not that much different from that of a prostitute:no permanent attachment, where the highest aim of life is to satisfy the fantasy of one's customer/client, drifting from one relationship to another? It's a good effort, but not yet a great one, saved only by the excellent acting of the father and son pair.
