What is the banker the office?

It is unclear which banker from The Office is being referred to, as there are several characters throughout the show who work in the banking industry.

• Charles Miner (played by Idris Elba) is a banker who temporarily takes over as the Scranton branch manager in season 5. He is strict and serious, often clashing with the more laid-back employees such as Jim and Michael.
• David Wallace (played by Andy Buckley) is the CFO of Dunder Mifflin's parent company, and occasionally interacts with the Scranton branch employees such as Michael, Jim, and Dwight. He is frequently responsible for overseeing the company's financial decisions, such as downsizing or restructuring.
• Bob Vance (played by Bobby Ray Shafer) is the owner of Vance Refrigeration, a company that partners with Dunder Mifflin for vending machines. While not technically a banker, he is a successful businessman whose financial status and reputation sometimes come into play during his interactions with other characters. He is also married to Phyllis Lapin, a sales representative at Dunder Mifflin.

Overall, The Office portrays various characters who work in banking or finance-related industries, but their roles and personalities differ greatly.
