in my town in new jersey, they opened a new dine in theatre thing where you have to be like 18 to get a ticket and stuff like that... for the people that been to the dine in theatres... if me brother (who's 18) buys the tickets for me and my friends, do we still have to have an adult with us or can they just let us in without one because we already bought the tickets? please someone help because im so confused....
