We Aim to Please (1934)

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.
