Had go to go a branch a couple times in the last year at a local credit union. Largely seems like tellers are getting busy work. There are not a lot of tellers present, and they appear to be doing other things on their workstation. So they get up to go to the teller window and help me out with my request, which usually involves them playing around with some archaic bank app on the teller machine and fiddling with the copier for a bit. A supervisor is always around who knows more of the business use cases and always seems to get involved either out of boredom or because they're the only ones who know how to do something.
