Ask them for coins that customers wrapped themselves and say you would like to buy all of them they have. Some tellers have to have their hands held.
I even said that and they still grabbed me empty rolls. I had to talk real slow and I almost had to draw pictures. I mean come on. Do y'all have any rolls of coins that people turned into you. Not the ones from the "Feds" (by the way I find that hilarious) its not hard to understand.
