Bad management

I use fnf the grove on almost a daily basis. I withdraw large sums of money in change for which i place orders. I really enjoy the tellers who assist me. My problem is that there is mostly two tellers. This causes massive delays. They provided for 4 tellers but will never utilize it. The poor tellers get yelled at and the branch manager never comes to talk to anyone. This is unfair to the tellers and clients.
