My local bank has a pneumatic tube. They have a limit of how much cash they'll send through at one time, a few thousand dollars. If you want more than that they're willing to send it in batches. The only reason I've been able to think of is something involving insurance/liability if the tube gets stuck with the cash in it, perhaps to limit the amount the service tech could possibly lose or steal. I should have asked the old manager about it before she retired, she loved to talk shop.
