Considering it's his reason for wanting to boot Maria, we already know the owner's against letting people come inside the workers, so it stands to reason that the last part of that was just supposed to be a test. In which case, it seems like a real dumb thing to follow the "you passed" with "barely, you're a far cry from maria" and no other explanation, right after honoka refused him.
Seems like a prime way to make the girl misunderstand the intent and decide she has to let customers do it raw anyway, if she wants to climb the ranks.
