What is the woman’s attitude toward the jazz ensemble?

Listen to part of a conversation between a student and a manager. (S = Student, M = Manager)
S: You know, originally, we were booked in one of the rehearsal rooms in the music building but then we switched with the jazz ensemble. They’re a much smaller group—and they said the acoustics, the sound in that room was better for them—so having us move to a bigger space like the Lincoln Auditorium seemed like a reasonable idea.
M: But now…
S: All that noise… I don’t know. I just wonder if the jazz ensemble knew what was going to happen…
M: Well that wouldn’t be very nice.
