Can you be charged after you leave the store, or after the day of the event? Yes. A decision to go back to the store or wait this out should only be made after you have personally consulted with a lawyer licensed in Oklahoma, who can advise you of the potential consequences that can occur, and who can advise you if he can intercede with the store on your behalf, or whether you could/should. Good luck.
