The Blue Idol(1931)

Baron Lóránt, now bankrupt for reasons for which he cannot be blamed, starts a new life in America, accompanied by Péter, his faithful valet. They both work as waiters in a bar. Things turn nasty when Lóránt recognises his uncle in one of the bar's customers. Embarrassed by his present job, he refuses to serve his uncle and is, therefore, promptly given the sack.
