Lots of deposit receipts get tossed out or simply dropped, without shredding. If you were a bank customer whose receipt was misplaced, would you want someone who picks it up to be able to see your account number and the date, time and amount of a deposit to the account? Many banks use that information in challenge questions when dealing with telephone calls from alleged customers, so when the information gets into the wrong hands, you've got exposure.
Have you discussed the problem with a teller whom you've seen process transactions so that the full account number appears on the receipt? In a discussion, you can learn whether it's simple sloppiness, a system design problem that makes the proper sequence ungainly, or a "real" reason -- the teller wants the customer to have the account number. If you can identify a teller who is doing it because the customer wants the number on the receipt, you'll know that you might need to retrain your customers and tellers (and give them both the reason for the security).
