I don't think I want to consume anything prepared by a staff of lunatics.
Lunatics are not known for meticulous hygiene.
Yeah, that would bother me too.
But they have to do
something, so as to learn self-esteem; work is good for them.
When I was manager of a privately-owned student union years ago, there was a big food-court in the building, and I understandably was in favor of hiring the handicapped. And I did. But they did the cleaning-up stuff, nothing having to do with preparing and serving food.
It worked well.
