I had a guy come in once and pay $120 to run 120 passes on each of his new LS Pulse TI steel blades on our ProSharp machine to decrease the height. I told him profiling could accomplish the same thing for less and he insisted that he just wanted them shorter, and he didn't want to relearn how to skate. I smiled, said no problem, and tossed them on the machine and let it do its thing.
When he came to pick them up, I asked him what to sharpen them to and he told me 3/8". I asked him twice to confirm he did indeed want 3/8" and he confirmed both times. I didn't even bother trying to offer him a more shallow hollow at that point. I knew it was a lost cause.
Moral of the story, some people really dislike change.
