I worked for BMW in Munich as a graphic designer, I often went into the factory to take pictures of the various stages of production. Once I climbed the steps up the production line, about two stories high, waiting for the right model to be transported along the line, to my delight the right model came along and I stepped forward to take the photos, I was really pleased that just at that moment the line stopped and I was able to take photos for 15 minutes until an enraged foreman flew up the stairs and pulled me away by the scruff of my neck whereupon the line started moving again. I had trodden on a safety plate which was there to stop the line to prevent people being knocked off the platform by the cars being transported along the production line. I had unwittingly stopped the whole production line in that hall and people were tearing their hair out trying to find the cause of the stoppage, I had cost BMW 30,000 Euros in production fall out, I thought the foreman was about to have a heart attack,.......safety first.
