<human>: Can you give me the gist of the text in a nutshell?

A year ago, a show was being filmed at my school. There were no huge celebrity names present, so it was just extras being filmed that day. From what I've seen, it was a huge protest scene where people my age were holding picket signs and yelling at the camera while "cops" were holding them back. 

Within the first couple of minutes of meeting the extras, I asked if this was going to be for an independent film. Eventually, I learned that it was for a show. But as soon as I arrived at the area where the crew and extras were sitting round, an extra nicely suggested that I leave before I get kicked out. So I left... for about ten seconds. 

On set, I talked to a bunch of extras and some crew members. The crew was very nice and the extras gave me advice on how I could officially be on a show (basically, get an agent). One of the crew members even thought I was an actor, so I rolled with it and said nothing (but I never got filmed). After some time, an extra offers me something from the food table; a cracker. I said yes an ate a cracker.

After about ten seconds, a crew member approaches me and tells me to leave the set, saying they can't have me eating their food. At which point, a campus police officer sternly demands my student card. He claims that they saw me eating from the table a few times and goes through the process of kicking me off the entire campus. During his conversation with his walkie talkie, the crew member comes back and explains how I'll be to blame if something were to go wrong on set (because I'm not an actor). Another crew member comes up to me (still thinking I'm an actor) and asks what's going on, resulting in the officer telling him the truth. 

After getting my name in their system, I was let off with a warning and told to "go home". In other words, I had to get the hell off of campus property. So I did what he told me and left the campus, not returning for the rest of the day to avoid trespassing charges.
<bot>: I ate a cracker from the set of a television show and got kicked off of campus property because I wasn't an actor.
