When I sat in the chair I explained what I wanted; "just trim the sides and leave the rest alone."
I don't know if she misunderstood me or just doesn't know how to cut hair any other way, but evidently she can't follow instructions.
After her initial pass up the side of my head with the #4 clipper guide, I told her that I didn't want it that short, and for the rest of the time she proceeded to tell me how much better this would be, then had the nerve to ask me if I didn't agree that this was better.
Needless to say, I won't be going back.
