No matter how frustrated Mortimer and his group felt regarding the Holy Knight Empire's treatment, Vaan was the wrong person for them to vent their frustration. Even if they were the Great Ratholos Empire's representatives, their positions were far beneath Vaan's.
If they want to complain to someone, it could only be minister-level officials like Minister Mistral or below.
They could not do the same to the ruler of the country, let alone the country's god. The country's ruler had to be respected, and its god had to be absolutely respected!
Unfortunately, Mortimer's group made the mistake of disrespecting Vaan at the start of their meeting by directing their frustration at him.
Of course, this was something Vaan planned and intended to happen.
Whether it was diplomacy or trade negotiations, they had to be conducted calmly. Becoming emotionally aggressive and irrational would only put the party at a significant disadvantage.
