Frankly, what Ayu did was mild compared to how things go in show business. That's just how it works when you're putting on a show. Sometimes entire numbers will get cut the afternoon before the show opens. This means that some people might even lose their jobs if they only appear in that one number. It cold and tough, but that's just how it goes.

If things aren't coming together quickly and nicely enough, they have to be either changed or cut. Ayu could have simply removed Chisa and Midoring entirely from that part of the show, but she didn't. She had Peco give them something else to do, so they will at least still be on stage. At the end of the day, that's all a dancer can ask for.

And the fact that Ayu went through Peco is a sheer matter of administration. Peco is the choreographer, which means the fabric routine was her responsibility--not Chisa and Midoring. Dancers are only pawns in show business. If Ayu went straight to the dancers, that would be like the general manager of a department store going to two clerks in the menswear department and telling them that their immediate boss (the menswear department manager) has to sell green socks instead of red socks. You don't do that--you work your way down through the bureaucracy, and Ayu is at the top of that.
