is one piece episode 22 filler?

Sanji attempts to charm Nami, treating her with a fruit macedonia, which gets him into an argument with Zeff. However, fog arrives, and the customers notice the arrival of Krieg's fleet.

Fearing Krieg's reputation, the patrons immediately flee the restaurant. Krieg enters the Baratie with Gin, begging for food and promising not to attack the ship if fed.

Against the wishes of Patty and all the other staff, Sanji agrees to feed him, giving Krieg a bowl of rice.
