A Cash Deposit Box will be provided for each ticket office and placed under constant
surveillance by the CCTV. Inside the Cash Deposit Box will be a small amount of cash in
small bank notes for the station staff to exchange during service hours. Upon the need for
small bank notes, the staff in the ticket office will request approval from the DSC to open the
deposit box and exchange the small bank notes with the revenue in the Cash Tray. Afterwards,
the DSC will go to the Ticket Office to collect the large bank notes, confirm the correct
exchange amount is accounted for and refill the Cash Deposit box with small change.
