[speaker001:] You're here to make a deposit, is that correct?
[speaker002:] Right. I'd like to deposit 2,000 RIB into my Current Account.
[speaker001:] No problem. Could I have the cash and your Bank Book, please? Oh dear... there seems to be some problems here...
[speaker002:] What? What's wrong?
[speaker001:] I'm sorry but 5 of these notes seem to be counterfeit. Look at this watermark, do you see it?
[speaker002:] It does look a little strange, I didn't notice that before.
