There's hardly any chance you will not end up with the offense. The cops do not "need to be called" right away. As I said, you can get the summons, and even a misdemeanor charge in the mail. You will likely get the order to go in for the mugshot/fingerprint if you don't already have it. Things are real laid back for prosecution of shoplifters like you but the results for you are just as serious as if they'd hauled you down to the police station and through you in the cell right away.
It's purely wishful thinking on your part that this is going away.
