is one piece episode 21 filler?

Baratie's patissier, Patty, denounces Sanji for his violent actions against Fullbody. Zeff also beats Luffy through the floor above, causing them to fall into the dining area below.

While Zeff, Patty and Sanji continue to argue, Fullbody attempts to flee, but is informed by his crew that Don Krieg, the most feared pirate in East Blue, has escaped their custody despite being starved for days. One of Krieg's officers, Gin, appears at the restaurant, requesting food.

Patty refuses to feed him as Gin cannot pay for the food, beating him to the ground and throwing him outside.
