I especially like Saturdays for picking up coin. Most of the bank's regular tellers are off and they have younger tellers working who are more eager to serve, things usually go smoother without the branch manager eyeballing me while I walk out with armfulls of bags & boxes. They mostly seem happier too since they only have to work a few hours.
Chase banks are open until 2 pm on Saturdays here, so Saturdays I hit up all the Chase branches in my area - they are usually a ghost town by 1:00 since I dont think most people realize they have those hours
