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 ( salon with his wife, Yvonne, said 5,000 people have taken the plunge so far.
