Would you be worried...legal advice?

It's obvious from you grammar and punctuation (or lack thereof) why you are working at McDonalds. Anyway, let your lawyer worry about the evidence, if the stories don't match he will have already caught it and will have questions to highlight the inconsistencies during direct examination. IF you didn't really hit them, and based solely on what you posted, this is a he said/she said case and the charges will likely get dismissed.
