Explaining a layoff without sounding bitter after 11 years as a bank teller

I have an interview next week and I am unsure how to explain why I left my last job as a bank teller. I do not want to blame the company. Do they ask follow-ups?

Say it plainly and move on to what you can do. Interviewers usually move on if you do.

If a company has been in the news for layoffs, you can mention that. Often the interviewer already knows.
