Regarding the food poisoning thing...I wouldn't be to quick to jump on that. Food poisoning has an incubation period of anywhere from 24 hours to 4 or 5 days.
If someone has a inner problem the chances are that whatever contact that was made was from something previously experienced. Many people make the mistake in assuming that what or wherever the last place they ate was the culprit. That's just not so. Think back to what you had done and where you had be a few days previous to the illness and you will probably find your source.
For the toenails, that should have been reported directly to housekeeping or the front desk. Like they said, most of the mousekeepers do not have a strong grasp on the English Language and therefore probably thought you were leaving notes out for yourself. It should have been caught automatically by housekeeping but apparently it wasn't. Also, and this is not a reflection on you folks, what kind of slob cuts his or her toenails and just leaves them on the floor for someone else to pick up. No class...no class at all! Someone else is an inconsiderate jerk and Disney has to take the fall.
