You dropped it on the floor. Do you eat it?

Not if I dropped it on purpose. Otherwise, probably.

Yes. Carlin had it right. We’ve got immune systems for a reason. Gotta give it a workout sometimes.

While I kind agree with GoatBoy on this (there was a study somewhere about the lack of dirt is not good) I have to say no, I won’t eat it. Damn, I won’t even eat left-overs…

In my house = Eat it
Someone else’s house ~ how well I know them.  I don’t necessarily want a chorus of “Ewwww...gross!” unless that would be appropriate.
Somewhere else: Depends on how seemly the place is.  If I’m confident, and since I don’t go places that make me feel otherwise, then I’d go for it.
So 9/10 says that it gets eaten.  Mmmm mmmm mmmm.
