Really interesting to see how P.T. Murphy handles his albeit very, very small number of poor reviews over on Trip Adviser (his reviews are overwhelmingly very positive, but there is the very occasional grumpy audience member). He answers them all, most often with humor, occasionally with blunt directness in kind, and here and there he even offers to guarantee a better time if they return for another show. I found his approach exemplary.

Thanks, Janet! :-D
