chairing, not sharing

Someone (kind of) smart has devised these "seat savers" to keep your bar chair free while you're on a bathroom break.

Seeing as they look kind of, um, paper, I don't know how well they serve their purpose.

It addresses a valid pet peeve, though.

Equally frustrating are partiers on the other side of the coin -- those who hold a big chunk of seats for friends who take 20 minutes to show up.

Thoughts?
