We don't count dropped off deposits under dual control. We also do not count ATM deposits or night depository under dual control.
For dropped off deposits, we "encourage" the customer to stay and if they do not, then the deposit is what it is. If the teller counts a different amount than what's listed on the deposit ticket, they are supposed to have another teller count it to verify. If they both agree the amounts differ, they reduce the deposit amount and both initial the deposit ticket.
I disagree with this practice as it has put our employees and customers in uneasy situations as mentioned above and it's not fun for either party. The customer doesn't know if their employee stole from them, if their employee cannot count, or someone from the branch stole from them. This is not good for anyone.
