it's not like you can drop off a bag full of cash with a note that says "we swears it is $10,000" without some human employee counting it. even with counting machines, they still have to sort it (unless I'm so out of the cash counting game that the counters can sort for you).
besides, you just wouldn't respect them in the morning if they did NOT take some money from you, would you?
I'm pretty sure my bank has a machine that counts and checks for counterfeits. I haven't seen anyone do a manual check in years, about as long as they've had the new machines. Of course there's still work involved, but it's mainly just feeding the machines and typing into a computer.
My bank has ATMs where you drop all your coins in a hole and the notes go on a stacker. It does all that stuff automatically
If there’s a damaged or counterfeit note it spits it back out. This is certainly 100% automated and it tells you exactly how much you deposited afterwards.
