Putting aside the message board issue, I have long opined that the quickest way to cure a desire for fast food is to actually work in a fast food joint.
My brother actually had the bleeding issue himself, but from a different angle. He worked at Taco Bell as a teenager and cut himself one time while on shift. The manager wouldn't let him tend to the cut so he just kept bleeding while preparing food.
One morning, a manager and I opened the froyo place I worked at. We found an enormous cockroad sitting on top of the food bins. She whipped out a can of Raid, sprayed it everywhere, and then told me to serve the food.
