Popeye and Olive open a diner, singing the title song. Alas, their first two customers are Wimpy (who actually gets them to fall for the "gladly pay you Tuesday" schtick) and Bluto, who orders 6 sandwiches and refuses to pay for them. This leads, of course, to a fight, which Popeye needs his spinach to win.

Popeye et Olive ouvrent un restaurant, chantant la chanson-titre. Hélas, leurs deux premiers clients sont Gontran (qui les fait craquer pour le "happy pay you Tuesday" schtick) et Brutus, qui commande 6 sandwichs et refuse de les payer. Cela conduit, bien sûr, à un combat, et Popeye a besoin de ses épinards pour gagner.
