Chouji takes note of Korra's restraint, and his smile of thanks makes that clear.

"If you've given the same speech over and over again for two and a half years, repeating yourself must get frustrating." Shikamaru was certainly more helpful to Chouji, but then, best friends are automatically 'worth the trouble.' "I get the impression that everyone from our world uses him as a walking information source when they arrive. A few people told me I should just ask Shikamaru."

The sheepish grin says it all. Chouji is well aware of Shikamaru's faults, but they pale in comparison to the respect he has for his friend.
