A truly sickening idea

Heard the true story about the low cost carrier that decided to sell advertising on their sick bags?
They did a deal with a photographic company who converted the bags to make them sealable and marketed on the side that all you had to do was fill in a section and, place your film inside and post it off.
The promotion did not last long as the photographic company was inundated with packages filled with......err what the bag was originally placed in the seat back for!
