One of the staff from the Wayside Tavern struts into the bank.
This person is often entrusted to carry a deposit to the bank and deposit it over the counter, and that is the full extent of their involvement with banking matters.
They are not a signatory or in any way authorised on any bank account belonging to the Wayside Tavern.
Upon fronting the counter this staff member enquires of the teller:
"Does my boss have any bank accounts that I don't know about?"
The teller gazes at their screen and taps some keys on their console.
"Yes, here's an account which you probably don't know about"
"I didn't know that particular account existed" says the staff member, looking at the screen, "I'd like to know what activity there has been on that account."
"There's actually a fair bit of activity" responds the teller, "in fact too much to tell you about. The account also maintains a significant cash balance!"
The teller then prints statements for the year to date (nine months worth), and hands them over the counter.
Clarification: The major sin in this tale is by the bank.
The staff member's sin is most minor alongside that committed by the bank officer.
