Back when I used to work retail part of my job when I'd work closing was verifying the manager's count for the cash that we'd them have to walk across the street to the bank to deposit. So I'm nowhere near as good as a bank teller, but I got pretty good at counting out bills quickly. Even I could bang out that in like 30 seconds assuming all I'm doing is counting out a hundred ten dollar bills. If it's gotta go through a counting machine first? Yeah probably another 20 ish seconds on top of that?
