The soldiers were utterly depressed upon seeing how decent and good the features of his mothership class was because their mothership was apparently built under the "preferences" of their captain which just plain sucked despite the amount of money spent on it. They mention that out of pure preference, their ship had a specific cooking machine installed in the kitchen that could only make good tea and pastries but every other kind of food and drink it makes just horribly sucks. Meanwhile, MC's kitchen had a cooking machine model that's known for being able to make good tasting food in general. I guess the officer in charge was thinking what if they bought their own ship and left the captain, but he was surprised by how expensive it would take.
