Worked as a courier for a photo lab that did film processing for major studios (in Hollywood, CA).
It was an after school job in High School (as I was 16 years old, was able to drive a car). Had to deliver the film for approval to a major Hollywood studio, but came straight from school and was starving, so stopped at a fast food place after picking up the film.
By the time I got to the studio, I was expected, and gave my details at the security gate. Drove in and parked where several PAs were there to greet me and that the film I had possession of, was, 'top top priority...'
Yup, it wasn't in the back seat, and I had no idea where it was. 
The head of the film company was furious and spoke to me on the phone saying, 'you life will not be worth living if you don't find the film in next 10 minutes...' 
I burst into tears, and the head of the film studio saw I was upset and she asked me where it could be. I explained that I came from school and stopped for food. She laughed and said, 'if you worked for me, there is food on the set...'
Found the film, got an after school job with brilliant boss and worked in their film lab on set until I went to uni.
