I would'nt do anything to her . don't stoop to her level. she will upset so many people, give her enough rope and she'll hang herself, you are not the first and certainly won't be the last, let somebody else sort her out she will one day meet her waterloo. I have another hairdresser open up the road from me, just over a year ago and she's a nasty piece of work, and has tried to get some of my client's. i'm doing and saying nothing, as i do believe she will upset people,I'm playing the waiting game. one day.
