That's ridiculous Mr Cat...surely you must know on any given day, far more warning letters are issued than OFPs. That policy would never work.
EK actually owns its own paper mill just for warning letter paper. Once issued, they are then recycled into OFPs, with the substantial balance of paper going to build housing for underprivileged children in Bangladesh through the company charities.
So embrace the worthy and ubiquitous EK warning letter. Much good comes of it.
