I woulda thought you're allowed to go to the cage and grab as many chips as you'd like.
Never hurts to ask at the cage when they are not busy, but you will be told no almost all of the time. I once tried to exchange 4-$5 chips for 20-$1s at the Paris cage when no one else was in line. Was told no and that I should go to the tables. It never hurts to ask though.
