In the summer of '06 I worked at a movie theater called Airport Cinemas. I had been working there in concessions and as an usher. One day while I was one of the theaters cleaning, I felt something poke me in the back. I turned around and there was no one there. I was at the top-most row, so I looked over the side at the aisle to see who the prankster was. There was no one there. I knew it couldn't have been anyone in the projection booth because the window made a noise when you opened it. Anyway, they could not have hit me in the back with something without leaning out of the window.
Freaked out, I went and talked to one of the girls who was working in the concession stand. It was between movies so it was pretty empty. When I told her what happened, she told me one day while she was doing a theater check, the movie was not on and suddenly it blasted on with no one in the projection booth. This theater was next to the one I had been cleaning.
Another story she told me was that a girl in projection was investigating a noise she heard in one of the theaters. When she opened the window to look out and stop the noise makers, she found the theater completely silent and empty. This theater was across the hall from mine.
The wing that this happened in is new to the original building. It was in this wing that all the stange occurrences happened.
