The "elegant" Darjeering goes full autismo when given a functional plantation of spices yet the Bakas are just happy to have won and don't even think of complaining when it turns out they need to put in some extra work.
That's because the Chihatan girls are hard working and enthusiastic plus they see silver linings in everything. For example, when they drew the number to be the team to face Kuromorimine in the 1st round of the Tankery tournament, they saw it as a good thing as to them, they get a worthy opponent right away. Most teams would shudder in fear at having to face Kuromorimine but not Chihatan, they cheered when they learned of this.
Chihatan defeating St Gloriana must've felt as great to them as the Japanese beating the snot out of the British throughout Southeast Asia felt to the Japanese early in the Pacific front of WW2 did in real life.
