Does this mean that Accounting may not be a good fit for me either?

I have a 4 year degree in Accounting. I recently took a bank teller job b/c I REALLY needed the money and felt like it was a good entry level position and that having studied Accounting it would make that job easier (SO WRONG about that one) and that it might boost my resume and help me get into Accounting field. Well that plan fell flat as I was let go today from my position as a teller due to cash countdown errors. So my question is does this mean or is it an inkling that Accounting may not be a good field for me to work in at all?
