I would think it would be difficult or unlikely for the teller to steal the money herself, as banks are sort of completely dependent upon having honest banktellers handle large transactions daily, as well as having safeguards in place to ensure the honesty of those tellers.

The place is full of cameras and they probably have a whole beaurocratic procedure for handling things like this, documentation, oversight by managers, etc.

I'm not saying it's impossible for a cunning teller to steal this money, but these tellers deal with much larger sums of cash, and if they havn't stole that by now, then this sum probably isn't worth risking their job over.
