Hey, I`m looking for a job as a teller…?

Hi, I`m a first year university student and I`m looking for a job as a teller at a bank. I have customer service experience, and I`m currently working in retail and would like to use my current job as a reference. I was wondering if I should put down on my resume that I am still working at the retail job… and if I should tell my current manager that I am looking for something else…
