Probably never. Like a kid at Grad Bash not graduating, being banned from the parks, and so on.. for something relatively minor like line hopping.
Which brings up the question.. at what point does the punishment vastly outweigh the "crime" ?
It's a theme park attraction that people are interested in seeing. What monetary damage is there in a leaked photo? An amount worth a termination (and no rehire and blemish on the resume) and park ban?
At some point you have to remember: It's a theme park.
