So when a popular movie comes out and you don't wanna pay just tell the dude taking tickets that your family or friend(s) is/are already in there. This works best on new movie releases that you know will be . like when Star Wars came out. Why you ask? because movie theaters don't count the front 3 rows as seats when they tell you the movie is . so those are basically always open. So lying to the ticket taker dude and sitting in the front row is double protection. They will thank you(in their heads of course)for not taking up a seat that someone that paid will need. Credits to original bud.
