The worst FAK I've used was from the school where I teach. Let me preface the story by stating that it's an "all-girls" school.
We took the girls out on retreat which involved an overnight cabin stay. I twisted my knee in the afternoon and looked for the FAK bag to find an emergency ice pack and an ace bandage. I was handed a gym bag that was empty save for about 250 tampons.
When we got back the next day, I met with the school nurse and our safety committee and made certain we had professional kits.
