Not a cinema worker.

Years ago, I went to see Tropic Thunder at the Cineworld in Nottingham. I had a Cineworld card and went by myself. It was in one of the big screens that had an entrance on each side.

As I was going in, this guy in front held the door open for me, but in a weird, almost theatrical way. I said thank you and went in. I sat on the back row, and the guy who'd held the door open for me sat a couple of rows in front of me but right behind a couple. There were plenty of free seats so it was an odd thing to do.

Forgot all about him until part way through he stands up and starts shouting at the screen. The couple in front must have been scared shirtless because he was kinda leaning against their seats to bear his weight.

He sits back down. He gets up and goes, I assume, to the toilet. I don't see him for ages until he starts doing something similar a few rows down. He gets up and moves around again. He does this a few times.

Eventually I get to the point where I am unable to concentrate on the film, but I'm also concerned he could have a knife or just be generally unstable, so I get up and go to find a member of staff.

My heart sank when I saw this puny teenage lad on the ticket-checking post. I told him what was happening, he was very understanding and said they'd be in shortly.

I went back into the screen through the other entry because I wanted to see where this guy was before I sat back down again. Suddenly the doors fly open and, I'm not joking, about 6 burly security guards come flocking in. I was so relieved. I told them I wasn't sure but thought it might be a certain guy in the audience who looked unassuming and seemed incredibly focused on the screen. At this, the audience began pointing their fingers at him!

So a couple of security guards approached and at that he leapt up and starts bouncing back and forth, I honestly thought he was going to attack them.

And then, incredibly, the security guard contingent basically surrounded him and corralled him out of the screen like he was cattle! It was done so smoothly. The guy was trying to escape the whole time but was bundled out of the screen right past me.

I returned back to my seat and one guy whispered "thank you" as I passed. I sat and watched the rest of the film but couldn't really concentrate. When the film finished, staff were waiting for us all outside, presumably in case anyone wanted to make a complaint.

Probably the only time I've been scared for my safety in a cinema.

Just to add, the women's toilets before ticket check were disgusting. Basically teenage girls hanging out in there for no reason. It's now a Vue cinema and I haven't been in years as we now live walking distance from a lovely independent chain cinema.
