What Do You Do?

As the blog post points out, what do you do with that seat if you are the stadium administrator?

You could rope it off, but that's a little awkward for all of those sitting around it. You could tell the ticket holder what happened and give him the option of  taking it or giving the seat up to the first I-Ain't-Scared-Of-No-Ghost fan. Or I guess you could take the extreme measure and shut down the whole section.
