Fish Pedicures

I am going to get me a fish pedicure one of these days since the location (8643 Richmond Highway) is closed to where I live. My only concern is that will they make me pay if my feet kill all the fish? From Delaware Online:

Fish pedicures are creating something of a splash in the D.C. area, where a northern Virginia spa has been offering them for the past four months. John Ho, who runs the Yvonne Hair and Nails (www.yvonnesalon.com) salon with his wife, Yvonne, said 5,000 people have taken the plunge so far.
