chunk: George becomes increasingly annoyed by the cheery atmosphere of his family and threatens to fire Mary Poppins. Instead, Mary inverts his attempt by convincing him to take the children to the bank for a day. George takes Jane and Michael to the bank, where they meet his employers, Mr. Dawes Sr. and his son. Dawes aggressively attempts to have Michael invest his tuppence in the bank, snatching the money from him. Michael demands it back, causing other customers to misinterpret and all demand their money back, causing a bank run. Jane and Michael flee the bank, getting lost in the East End until they run into Bert, who is now a chimney sweep. He escorts them home, suggesting their father does not hate them but has his own troubles to deal with. The three and Mary venture onto the rooftops where they have a song-and-dance number with other chimney sweeps until George returns home. George receives a phone call from his employers, telling him to meet them later for disciplinary action.
