I have been banking with this credit union for a long time now. It seem like for the past few years now there "customer interactions" has not been too friendly. I am a very outgoing and nice polite person and some tellers look so unhappy to be there and sometimes even rude. Some tellers don't even smile at you. It's so bad that I get better respect and service from the ATM at the branch.
