I vote for eat it and hope for ice cream.
Has anyone ever actually found a spider in their cone, or known someone who did?
There are probably a few tiny parts of insects in the cone and ice cream anyway. And having eaten ice cream cones for a lifetime, I’ve yet to get anything untoward in one, let alone a spider. There’s probably a greater chance of dying in an automobile accident while driving to/from the the place where you bought the cone.
