Don't apologize for asking questions...it's sorta the purpose of this entire forum. No questions means nothing for us to rant and rave about...
As for jail, I highly doubt they're going to put a 19yr old kid with zero criminal record, committing his first misd. offense in the pen. Prisons are not designed for that.
As for pleading guilty or not, I would consider retaining an atty. This could affect your future. If they have you on camera shoplifting, the case if pretty much open and shut and it may seem assanine to plead 'Not Guilty' when you clearly were...but that's for a jury to decide if and when you decide for trial. But coughing up the cash for atty is a very wise decision, probably the best money you'll spend in your life (as of yet).
