i have an interview tomorow. should i lie about being fired from last job?

[Tigreen]

I was fired from a retail store about a month ago 12/05. I applied last week to a smaller retail store. On the application I said I'm still working there. Tomorrow I have the interview. To add to that both stores are on the same shopping center. This job pays less than the last, so it might be hard to believe I'm willing to switch willingly. Should I say I still work there.
