If you're familiar with True/False's Q System, most of this is nothing new:
No more than 4 free tickets will be given to one person.
A free ticket guarantees you a seat till ten minutes before showtime, but not after.
If all tickets have been distributed and there are open seats at 10 till, we will start seating the theater from the waiting list (queue). Ticket holders will continue to be admitted at this time if seats are available.
No latecomers will be admitted after the feature has started (often there are no trailers before free or community films).
This policy allows us to start on time and give the audience a distraction-free experience.
