Later in the movie Captain Mason is arguing with an server in the Chinese restaurant about his share of the bill, arguing that he only had a shrimp boat. He had at least one item more, for which he asked only one of, and the server tried to sell him three. So he did order more than one item.
Although a Jewish funeral and cemetery are shown at the opening of the film, as evidenced by the tombstone inscriptions, flowers are seen accompanying the coffin. This is inconsistent with Jewish burial tradition, where flowers are never used in the funeral ceremony.
Credits show a character description "paparazzi" and lists one actor's name. Paparazzi is the plural masculine form of the Italian noun "paparazzo." Because there was only one photojournalist hoping for a picture of someone famous, the noun should be in the singular form in the credits. Therefore, the character's description should correctly be listed as "paparazzo."
Early in the film Joey tries to sell a car to a widow at her husband's funeral. After she refuses and admonishes him, he says something to the effect 'not every sale works out.' A failed sale attempt is not a sale not working out. More appropriate would be to say that not every pitch or sales pitch works out.
