From Casablanca (1942).
Captain Renault (Claude Rains) threatens to close up Rick's (Humphrey Bogart) Blue Parrot club.
Rick: How can you close me up? On what grounds?
Captain Renault: I'm shocked, shocked to find that gambling is going on in here!
[a croupier hands Renault a pile of money]
Croupier: Your winnings, sir.
Captain Renault: [sotto voce] Oh, thank you very much.
[aloud] Everybody out at once!
