When Pablo, Brigitte and Walter are in the Chinese restaurant, Walter finishes his aperitif in one gulp upon receiving it. However, when Pablo suggests a toast, Walter's glass is full when he picks it up. Then, he puts it down, empty, although he has not drunk from it.
When Walter punches Pablo in the restaurant and then Pablo gets up, his sleeve is up. At the next shot his sleeve is normal.
During the restaurant scene, Pablo steps onto the table to punch Walter. It is clear from the angles of his knees, and the height of the table, that he stepped onto an intermediary platform that would not be in a restaurant.
