From the text:
Sheila: (distressed) I went to the manager at Milwards and I told him that if they didn't get rid of that girl, I’d never go near the place again and I’d persuade mother to close our account with them.
Inspector: And why did you do that?
Sheila: Because I was in a furious temper.
Inspector: And what had this girl done to make you lose your temper.
Sheila: When I was looking at myself in the mirror I caught sight of her smiling at the assistant, and I was furious with her. I'd been in a bad temper anyhow.
