While we are talking about movies.....
My first real job was working at a Drive In theater in the concession stand. Within a month I got promoted to projectionist. This drive in had the old Simplex carbon arc projectors where you had to keep an eye on the rods and adjust them, and then change them every few reels. No platter system and halyde lamps here!
I'd get my friends in, and we would sit right outside the projection booth so I could still hear the "change projectors" bell. My boss was a great guy, and really didn't care what I did, as long as i kept the movie rolling. Afterward, we would stay on the grounds, and crank up the in house stereo. Three hundred speaker surround sound! Most fun job I ever had.
