Cutting in the ticket line of hair.

No, people can cut in line but only if you can still get a ticket.

what i meant is is there any enforcement that prevents people from cutting in line

As yankeefan007 said, once the Public workers get there they are very good about spacing themselves and patrolling the line. Plus most people in the line do rat out cutters ~ up to and including people who "are just there to talk" but try to stay in line later. When the Pubilc security people see someone who wasn't there before they will tell them and the person with whom they are talking that they have to go to the back of the line and make sure they do. You are allowed occasional bathroom breaks, but they make it clear it's to the bathroom ONLY. Not to the Starbucks outside the park or anything like that.
