Pumpari od Zlaté podkovy

A well organized group works at a petrol-pump: the chief Vávra, Engineer Stejskal and Karafa. Work is done quickly and the profit in their own pockets grows as well. The fourth employer, the old Dvorák, does not want to have anything with these "fiddles", therefore he decides to change employment. To this situation comes the young man Cerný. Vávra hesitatingly explains him the way how to increase the basic salary. Cerný learns quickly, grasps the system of sharing ill-gotten profit and asserts his right of the equal share. - IMDb
