Janeway unknowingly insulted the consul when she put her hands on her hips, which the Tak Tak interpreted as offensive. Neelix was able to resolve the situation since he knew the customs of the Tak Tak.
When Janeway returned to the USS Voyager, she found it infested with macroviruses. The Tak Tak Consul decided to purify Voyager by destroying the ship, as the Tak Tak had no cure for the virus. Janeway was able to convince him not to proceed with the purification, as she had developed a cure for the virus and promised to share it with the Tak Tak. The cure was successfully administered to the crew, and the Tak Tak Consul was astonished. Before he left Janeway put her hands on her hips again (after terminating communication) to purposely insult him for trying to destroy Voyager. (VOY: "Macrocosm")
