i used to work in a movie theater in high school, same theory applies. you can actually walk right in without a ticket and no tricks, just confidence and a sense of entitlement. my coworkers would never stop people with the balls to do it and it happened many times.

walk close behind a group of at least 2 other customers. as their tickets are being ripped just keep walking past them at a normal pace, head facing forward, and without making eye contact. they will notice you but do nothing.

go ahead and try it with a legit ticket in your pocket you can show them if they do stop you.
