What scene does Aisha make publicly in Section 6: Chapter 8? Why?

When Mr. Rashid claims they will have to wait, Aisha slams her bag on the floor, claiming she hired him to do the best job possible, and while they may not be as rich or educated as his other clients, her family still matters. Nadira follows Aisha out of the office, and Aisha says they must convince the authorities that they are making a mistake themselves.
